About
ADHD Weapon System: the core game loop is about rapid progression through weapon powerup switching (19 weapon sets, each comprised of an Auto Shot, Rapid Shot, & Power Shot, totaling in over 57 weapon types). You've never flow stated in a shmup like this.
No BS Controls: Whether you're D-Pad, Arcade Stick, Keyboard, or Analogue stick, you're always in full and precise control. Whether dodging waves of flaming baby sword-wielding demons (Gradius) or full-on giant kaiju demons spewing massive waves of bullets (DeathSmiles) to macro or micro dodge, you'll rise to the challenge of flowing as one with the machine.
Every run changes with the Monster Trophy system, spawning monster surges as you get better at screen-clearing enemies
We've had players play for over 100 hours before seeing everything (hidden mini bosses, additional endings, and more)
Over 40 hand-drawn and animated baddies with custom death animations
58 minutes of synth chip tune music from legendary composer Chris Huelsbeck (Rogue Squadron, Turrican Series, The Great Giana Sisters, Tiny Vikings & More)
Gradius V playthrough length, great for when you have an hour to kill
Additional Game Modes:
5 Minute Caravan score attack game mode
9 Hells Boss Rush (unique boss encounters and not rehashes from the main game)
Race Mode

Interstellar Sentinel is an action-packed shoot'em up that takes you on a sci-fi fantasy journey through legions of monsters, demons, and cosmic mind-ripping entities.
I grew up playing games like Life Force on the Nes (Salamander outside of the US), Gradius, R-Type, Super Aleste, Einhander, Ikaruga, and more. Interstellar Sentinel features tight controls, digital & analog stick (PlayStation & Xbox controllers verified), stylized beautiful art with lite anime inspiration, and a rewarding experience that becomes more challenging as your skills grow.
Also known as being "in the zone," this mental state refers to a player who is fully immersed and intensely focused on a video game. In this state, the player experiences a seamless and effortless gameplay experience, losing track of time and achieving peak performance. It is characterized by a perfect balance between the player's skills and the game's challenges, resulting in a deeply satisfying and enjoyable gaming experience.
Monster Trophy Enemy
A hand-crafted dynamic difficulty system. This system provides gameplay depth, layering, and secrets. The more your skills with piloting and weapon systems, the more the game changes to provide you with new experiences, including hidden miniboss challenges across the levels.
This game will ignite your senses from the very first moment. Excitement will course through your veins as legions of demonic entities swarm towards you, your fingers will dance on the controller, flight maneuvering with precision and speed. The intense action, visually stunning graphics, and immersive sound effects will keep you at the edge of your seat, fully engaged in fast-paced battles.
Your Gun Portals are a powerhouse of deadly weapons designed to keep the core game loop changing and challenging with never-before-seen weapons in a shmup. Over 55+ weapons are at your fingertips; as you collect weapon power-ups during intense battles, you'll experience a surge of empowerment. The feeling of turning the tables on hordes of enemies with a barrage of laser beams and missiles is simply euphoric, making you feel like an unstoppable force. Experience the unique flow of weapon cycling and adaptability to become a master of battle rhythms.
Mesmerizing environments that will draw you into its sci-fi fantasy universe. From giant kaiju bosses in cosmic landscapes to undead guardian dragons, each level is intricately designed to create an immersive experience. The seamless integration of music and sound effects adds another layer of immersion, making you feel like you're part of an epic battle opera.
Amidst the chaos of intergalactic battles, you'll discover moments of zen-like focus. As you dodge incoming projectiles and navigate through tight spaces, you'll enter a flow state where your mind and body become entirely absorbed in the gameplay. This meditative quality allows you to momentarily escape the pressures of daily life, providing a welcome respite and a chance to recharge. I bet you never thought of a shoot'em up in this way.
Earworm Original Soundtrack: Legendary original composed soundtrack from the brilliant mind of Chris Huelsbeck (The Great Giana Sisters, Turrican series, Tiny Thor, and more) comes a modern retro tribal drum synth chip tune feast for the ears that captures the struggle of heroic friends straightening out a twisted world
Rapid Shot, Power Shot, & Auto Shot spatial design provides spatial choice gameplay. How you position your DrBossKey relative to the weapon points allows for advanced piloting techniques to dish out damage. Advanced techniques like point blanking (think of it like sticking a shotgun in the face of an ugly demon and pulling the trigger for maximum impact), Power Shot alignment (charge up, 10x more powerful shot compared to the Rapid Shots, often with piercing), and Auto Shot utility (near field damage, homing missiles, plasma stasis damage fields) give a great mix of core gameplay choices.
Your wingsuit reactor core vulnerability point is the key to weaving through the bullet hell battlefield. Don't be intimidated by some of these bullet hell fields, they are not as hard to navigate with a modern player hit box as you would think.
Rapid Shot, Power Shot, Auto Shot Form a "Weapon Set"
19 Weapon Sets & over 55+ weapons to be mastered
Unique core loop gameplay experience with a high rate of weapon shifting that ties back into all key systems. Flow is in mastery of the Gun Portal weapon systems
Gun Portal weapon sets are designed to scale in utility and versatility, with your base weapons being powerful to avoid “Gradius syndrome,” where losing your weapons makes you want to start over because your basic weapons feel like throwing wet noodles at hungry demons
Weapon Downgrade system, you can dump your weapon sets to keep playing with your favorite weapons for the situation. Dumping weapons also keeps your chain combo multiplier going and offers great risk vs reward scenarios
Destroying enemies unleashes their soul bits, monster soul essence, which powers your super weapon
Generate temporary invulnerability field
Cancels enemy bullets to generate higher score rewards
Produces Monster Star Gems to collect for bonus points
Unleashes the stored-up monster soul essence, which in turn regains soul essence, which can let you chain supers together
A full super weapon bar is a terrible thing not to unleash on the very plague of demonic enemies that you harvested super weapon energy from
Part of being a badass flying hero is knowing that your suit can take a hit or two, sometimes even strategically (hint hint)
Screen clearing enemies and achieving high scores produces Monster Trophies. Monster Trophies spawn more challenging and unique enemies
Monster Trophy Medals are earned when defeating Monster Trophies, which in turn power up your Chain Combo meter
The Monster Trophy hint system gives you a sense of how much more there is behind the curtain of the universe
7 possible ranks from D to S+ tier ranks that drive dynamic challenges, minibosses, and may even unlock the secrets of the universe
A dynamic score system that factors in Chain Combos, Monster Trophy Medals, Boss Time Bonuses, rewards, Power-up, Surviving, and more that rewards players who are not traditional score chasers
Score transcends mere digits; your accumulated points serve as both additional lives and the path to advanced gameplay rewards like mini-bosses and the glowing admiration of your Twitch followers
The Chain Combo system starts when destroying enemies and you have to keep destroying enemies every 6 seconds before the chain combo meter ticks down to keep your high score going for maximum fun and prizes
Each level contains the pure joy and anxiety of surviving. Rule number one of Pacifist Mode: survive; rule number 2, see rule number 1
On completion, it provides higher-tier powerup weapon set drops
Gain an extra life when activating it
Gain a temporary core shield hit point
As your skills progress, your score is the key to measuring that progression. Chasing the one credit clear (no continue screens and beating the game), and S+ tier ranks is a goal worthy of your gamer mantel. Etch your initials into your Hall of Fame

As a great fan and player of Arcade titles, especially SHMUP, I have to give a negative rating followed unfortunately by a refund. However, I want to explain why: - The main problem is the poor visibility of the Player, usually the center of the player's movement is focused on the weak point, but here it seems that the center is between the frontal weapon and the vulnerable point, this makes moving the Player unnecessarily complicated. - The difficulty needs to be totally revised, there are moments in which it is practically impossible to dodge shots and lives are lost without the player's skill counting for anything. - The spawn of enemies is arranged randomly and with a few exceptions, it is not designed to create interesting situations. - The battles with the bosses are too long and also poorly balanced, you go from having lots of "safepoints" where you are practically never hit by bullets to moments where you have nowhere to stand. - The weapons are poorly made except for a couple that are fun but are not designed based on the gameplay. These are the main points that I would like to share with the Dev to get inspiration and maybe improve. Overall it's a fun game but not suitable for those who know what a SHMUP is.
Interstellar Sentinel is a well designed SHMUP with a pretty, yet trippy animated style, I would describe it as a space opera with comedic undertones. The gameplay is responsive and plays well with a cool arsenal of weaponry to your disposal. It should take you around 1 hour to complete unless you want to go the extra mile to complete every objective with the highest rank. Overall, the team did a good job here!
As a man who grew up in the 80s playing games like LifeForce and Gradius, this took me back to my childhood and then smoked me with a smart bomb of awesomeness! tight, intuitive and precise controls. fantastic enemy design as well. honored i got to play test it, and cannot wait to see what the future holds for this game and any others from this team!
Esse game me trouxe uma nostalgia dos Arcade antigos do Master System e Mega Drive. Tem um bullet hell insano mas, não achei o game punitivo, ao morrer eu voltava no mesmo lugar. O que perdia era o Score. Tem uma variedade de tiros e inimigos bem interessante e jogando no modo normal eu cheguei proximo de finalizar o game com 1h de jogo. No entanto, tirei " C e D " em todas tentativas. Eu precisaria jogar mais para ver os segredos do game e fazer mais pontos. Recomendo para fãs do gênero.

I'm a bit biased, but playing through this game still tickles my shmupping fancy. The core game loop of alternating between top and bottom weapons depending on their health coupled with a huge array of weapon sets that you are constantly upgrading through keeps the moment to moment gameplay focused. Legendary soundtrack by Chris Huelsbeck really slaps, staying with you long after your play session.
No geral, o jogo é um shooter com muitos elementos que lembram jogos da minha infância, achei interessante e com opções que tornam o jogo atrativo pra experimentar os power ups, armas diferentes, ver a diversidade de inimigos e cenários! Gostei bastante, joguei por 1h e foi o suficiente com a dificuldade mediana pra quase terminar as fases, morri na 7ª. Pontos Positivos: - Variedade de Power Ups - Diversidade de Cenários - Variedade de Chefes e Inimigos - Opções de Dificuldade: Achei legal ter diferentes quantidades de vida, com 3 é realmente bem difícil e com 30 mais que suficiente. - História legal Sugestões de Melhoria: - Legendas e UI Multilíngue - Mais Cutscenes
If you're looking for a game that is a great callback to the glory days of the arcade, or want to experience what you've only heard about from the older generation about those days, then look no further than Interstellar Sentinel. This game is a love letter to the great Shoot-Em Up franchises from the past. What amazed me the most about it was how much I kept wanting to play it when I was away doing other tasks, and I can't see anyone who's been jonesing for another SHMUP not giving this game a try. Recently, I completed the 1cc Challenge given to me by the creator of the game. For those who don't know, if you can complete the game on the hardest difficulty without continuing, the creator will send you a pin to commemorate it. Please enjoy, and I can't stress enough how fun it is to play this game - https://www.youtube.com/watch?v=J0IAr5ua-H0
Great horizontal side scroller shmup game created by Uplifting Goat LLC. with very cool Gothic visual style and fancy explosion particle effects. What actually amaze me a lot is when the game getting harder it harder, I don't actually feel overly stressed because when you die, it is not the end of the world, which to me as a casual shmup player is very friendly. Can't wait to see the sequel Interstellar Sentinel II!
I had the hugest smile the entire ride! It's taking me back to playing Super R-Type on SNES with my younger brother. You've absolutely nailed the nostalgia factor, and for that I'll never be able to adequately thank you. The gameplay and soundtrack together are such a poignant love letter to nostalgia and gaming days gone, but living forever in our hearts. You've given us a true gift.
I like it very much!! this was introduce to me by one of the game testers, its very entertaining. this game reminds me of those old school spaceship shooting game. give it a shot and you'll have fun.
