Really good so far but does appear they are still working on it. Very happy with the game for only three dollars. Better graphics than most bullethell.
¿Qué decirte? El género "Survivors", de auto disparo, cuya única interacción es manejar al personaje esquivando tiros y bichitos... con stats únicamente conseguibles a través del grinding. Muchas partidas, y comprás cositas. Ya se ha visto, si. Pero te engancha. Es paco puro. Extraño las épocas donde tenías que tener algún tipo de estrategia más allá de huir de bichito como rata. Me parece más bien que no soy el público de este estilo de juegos. 6/10
This is a mostly competent Vampire Survivors knockoff. Play sessions can be much shorter, ranging from 3-20+ minutes instead of mostly 30+. Some starting weapons do not feel useful enough to facilitate survival, and maximum movement speed is still quite slow. I've only just unlocked the 3rd area - Atlantis Lab.
Picked this game up on a whim not expecting much, loaded it up and 6 hours just flew by. It's not too complex, but there's enough variation in characters and builds to keep things fresh for a little while. I'm really enjoying it so far, highly recommended for its price!
The environment is an interesting take on bullet hell/survival games. Well, mostly. You are in a world where aliens have invaded. Your primary task is the saving of the planet. This means that you need to stay alive as long as possible, collect items, die and do it all over again. Given time and enough playing and you might just make it. First, the graphics are quite nice and game play runs smooth. You will eventually start finding health, but be careful because the location of med-kits are unpredictable. The offensive skills of your avatar will grow as the game progresses. This is a fun game that can provide hours of enjoyment. Just keep in mind that it takes some time to get your avatar strong enough that they can stay in the game for more than a few minutes. I always consider my game purchases by how many hours the game can be played and its cost versus other forms of entertainment. Get the game. You won't regret it because it is a lot of fund. Great job and kudos to the developers. Cheers
//!!!\\ NO CLOUD SAVE OPTION Gameplay is fine but content is not there. If this game take more than 2-3 hours to 100% is beacause you can only progress 3 "research" at a time. Without that, one game with every character and you're done. Also, at 13h I'm only missing 2 achievement, global money and kill, and I am at 1/10 for money and 1/7 for kills.
Photon Blaster is the key
Poorly balanced, frustrating to play, and clearly a lazy port of an already crappy mobile game. Feels like a total waste of time, not even worth a buck. Avoid.
A very fun, simple, and addictive survivor-like.
game is dead no updates since publisher acquired. dont buy
