I really like the soundtrack. I found myself humming the tune after just a few minutes. Unfortunately, the colour palette is very monotonous and that combined with the abundance of diagonal pixels makes the art style very hard to love. I feel like every enemy has a little too much health. I also can't for the life of me understand why you'd want to buy bat wings. Is there some hidden use to them that I wasn't told? I feel like the shop could have benefitted from power-ups for your gun.
