Really good sound/design and UX, it has good bones, that could definitely turn into a something with a bit more thinking, if it included some more meaningful decisions.
The randomness of a wheel does make it tricky to balance, I think a greater focus on the ability to modify the elements on the wheels may help the player feel less of a sting when the randomness doesn't go their way. Even if its a simple as the player choosing where the negative spots are placed on the wheels, they might feel more in control when it lands on it.
Great work!
