Good game, tho a bit short, I've played for a total of 15,6 hrs and have unlicked all unlockables, finished the game now twice. Devs are very active and I had an issue with a gamebreaking bug, that was resolved within 2 days or so, the fact that it's a 2 man team behind this and is crazy, hopefully they will add some more content in the future. I have a slight issue with the achievements at it seems my last 2 achievements is dependant on each other, otherwise a nice timesink for when you just want big explosions and a lot of enemies to kill, would love to see something like endless mode or something.
Really fun game to play
This game is extremely re-playable!! It's so much fun! Just try it, once!
Fun game
Pretty fun. Short though.
Addicting Arcade Fun! Sharp visuals, unique sci-fi witty art design; Deeper than it looks at first glance. It hooks you the way plinko, slots, or a strong roguelike does—easy to start, hard to walk away from. Cosmic Coliseum keeps things fresh. You start off running laps around the map and dodging enemies, progressing as you get stronger and more knowledgeable using less space on the map until you're just a God. And just when you think you’ve found the perfect build or weapon combo, the game shifts—new enemy dynamics, different pressures, and suddenly you’re adapting again. It never lets you coast. The progression feels real; you grow stronger over time, not stuck in a flat loop. Boss mechanics, varied maps, and a wide spread of weapons give it more depth than most arcade-style games. Only downside: it will push your PC hard during long sessions. Six hours disappears quickly, and your system will feel it. Great care was taken in balancing, mechanics, design etc.
Good little game. There's excellent depth in the weapon builds combined with visually pretty changes to the way the bullets look. Can be tricky at times, but with the right builds you can pretty much be invincible. Side quests are decent enough and overall, this game comes across as a huge polished effort from a team of just two people. If you liked Vampire survivors, then this looks 10 x better and has a very similar way about it. Highly recommended.
Extremely fun game with a lot of great options to play different builds/styles. Really satisfying to ramp up your build as you level up, and pretty mechanically approachable while having great capacity for skill expression
Fantastic game. Played the first rendition and it was solid, but the full release is awesome. Characters, guns, perks, everything was well designed. Art and music were beautiful. 10/10.
Lovely game. Give it a jam bois. Max it. Live it. Be it.
