I love the music and how the game looks ! :)

Cool Idea, but very glitchy.(for example, enemies  can shove you out of the spaceship and while they can just fly over walls and outside into outer space, you have to glitch back in)

Kinda doesn't fit the theme, since enemies are usually out of your controll.

I like the art style quite a lot.

I would recommend a better feedback on hitting your enemies, since that seems very bare bones and isn't that fun. Some Sprites with a sound or even screenshake would be cool. But currently it feels like you are shooting BBs. You could also make the gun stronger instead of making you shoot like 10 times per enemy. And provide less ammo.

Pretty cool looking!
