I enjoyed this a lot. Getting the first few upgrades took a while but continuously upgrading the wheel was fun. I like that you can switch out pieces depending on how much money you have, adding a bit of strategy (e.g. at one point I made the mistake of putting on a multiplier when I was low on money and ended up multiplying my debt over and over). I feel the never negative upgrade that you get removes some of the risk, but it's nice that you can just turn it off, plus you're probably close to beating the game at that point anyway.
Visuals were really polished and the music was nice. As others have said though I found the font really difficult to read at times, especially on the slices, I also felt that switching the pieces took a bit more time than it needed to.
But this is a really well put together and fun game, great job!
