Firstly, I absolutely love that song and almost used it in my game. Secondly, great idea for the game mechanic even if it ABSOLUTELY is doing a number on my wrist trying to keep the cursor in the circle! I did find it a bit difficult overall, but still a fun challenge. Nice work!
(SMALL BUG: I had a hardlock freeze after my 2nd retry. I was at 17.1% and it shows "YOU LOSE"/ main menu/quit but won't let me do anything. I reloaded and the next 2 times I died it also froze if I tried to choose quit)
