Nice job ! Nice concept, and the art is simple and efficient too ! I liked the fact that there were different musics for the different parts of the game.
Unfortunately, i managed to pass the first level without moving because i had no time to react to the projectiles anyway. Also, it is possible to reload while shooting in the third level so the rifle is op x) Finally for the final boss fight the boss somehow softlocks on the right side of the level while shooting very fast so it's impossible to pick up the ammo there without losing health ...
Anyway that was overall a good job from your team, keep it up !
