I only managed to get to the second level and BOY IS IT HARD. This difficulty spike is just too unforgiving and I don't know how you're supposed to do it, if at all. Regardless, having the keys affect directly the rotation acceleration and not the angle itself is a neat take on the theme. I love that you decided to implement an in game radio, but having someone else playtest your game could allow for people to enjoy the rest of the content that I believe you have created. Prioritise! Good luck.
