I like the idea with the wheel and the upgrades a lot. Do you plan to add temporary modifiers/buffs/debuffs that affect the speed of the wheel?
once i have the art for the player done, ill make a knockback/flinch system that will include wheel speed debuffs, also the wheel has been rebalanced in version 0.2, so maybe give it another try. or wait for the full release in February i suppose.
