I liked the take on the theme for your game, where you literally spin to win.
I was confused on what actually made the wheel turn faster, an indicator giving the angular velocity before dropping would help, especially since I was experimenting with different ways to make it go faster and didn’t know which was best until release.
It took a while to grind for the upgrades (or maybe I was spinning the wheel wrong). Some cheaper ones (or stacking of existing ones) would have helped smooth out the gameplay.
Overall a solid entry that I enjoyed playing. I’m a sucker for incrementally type games, this one has potential if you keep developing it. Good job!
