Looks really cool!
love the music and the effects, the screen shake and sound effects are really nice. There is a bug that when I die it still continues to play, I cant move but the game goes on and keeps on shooting and stuff
it feels pretty polished and good, I think that the amount of health that we have currently is good, maybe a tutorial stage would be good?
For me it's a hard game, I didn't manage to win a fight but I will keep trying ( Also I am not so good in bullet hell games so take that into account)
