I gave this game an almmost perfect score, because it's just really that good!
The only feedback I have is that the spin jump seems to still require you to spin the mouse even if you enable click to jump. To be honest, I think click to jump should be the default and holding it for longer should enable the spin, because for my verticle mouse, the spin is just really tricky.
Other than that, it's funny, beautiful, engaging and it fits the theme, and the soundtrack rocks too. Really good job!
