I'm a sucker for pixelated trails. The animated buttons felt fun to click. Neat how spinning in different directions produced different currencies.
Played to level 7. The robot spinners seemed to get far outstripped by the manual spinning vs their relative costs. Even after leveling up the robots so that they cost more than crits, spin speed, and coin gain, they didn't seem to make a dent in my automatic gains when I sat back and watched for a while.
Neat little number go up generator. Might be interesting to have multiple cranks you have to keep simultaneously going via player-driven momentum instead of full automation.
