This game's sounds are very tedious and just awful to hear constantly repeated, it would've helped if you didn't choose such harsh sounds, or gave them a bit of variation. Also the UI looks very basic, which isn't necessarily bad, but it doesn't really match the rest of your game. Also there is no ui to know when your out of energy which makes no sense, and having the enemies have solid collision feels really weird. Also I don't know where your using the spin in it. Also a bit faster would really help with more enemy types.
