This game is fun as hell. Something like a mix of space invaders and rogue-like games. The mechanics are simple but create complex situations and that makes every level feel like completely unique and replayable. I like how balanced the power-ups system is, and the fact that your ship loses its collected weapon after each death makes you use different tactics. I like the variety of enemies, each one requires its own strategy to kill 'em. And the co-op adds even more potential into this game! The music is also perfect and nostalgic, the visuals fit well and doesn't distract you at all.
I can totally say that this game is designed well, I'd definitely recommend everyone to play it. For better experience, play with your friend!
I wish all the best to the developers and I hope this game will get recognition it deserves.
