There are a lot of types of games, but there are only two types of developers. I don't know if you're a serious developer or an "intentionally make it as bad as possible for lols" developer (long title, I know).
Serious dev: Maybe you can improve the visuals a bit, the colour scheme is a bit painful to watch. Perhaps add some background music as well. Other than that, not bad at all.
Lols dev: What are you doing man? Do you have any clue how much of a pain in the bottom rotation is (in Unity atleast). There is no way that a bad dev would be able to manage that. It should rotate in one direction, then stop and start rotating in the other direction, then all of sudden teleport to the normal rotation again. Also, all of the limbs are the same colour! How is that even possible? I expect atleast one of the limbs to always be the same colour and a random sprite in the scene to take its place. Overall a decent attempt at being bad.
