Well I think I have exploited your game xD
If you spam one arrow key, you can wait at the center for an infinite amount of time until the spinning slows down. In the beginning the game is a bit too hard, so I would recommend to make it easier there and slowly increasing to an insane difficulty.
And yes I realized that even here on itch you can see that my name idea was not original and I need to find a new name asap and also leave my old name which I'm using here tmp.
Besides that awesome game and I'd love to see it evolving
