This game could be really good, the player character is really cool, but it's too much of a grind. You can die really easily (which is a good thing for me) but you shouldn't lose everything when it happens, especially given the cost of things. Also the floor/background textures look wrong, not enough distinct from the player and enemies. Some dynamic lighting and shadows would help a lot I think, I believe a darker atmosphere would suit this game a lot. The gameplay feels good though, the theme is well implemented, and the projectile effects are cool, good job there!
