Neat game. Quite simple in its design, but the execution is done very well.
The only improvements I can think of for it would be to make the UI a bit clearer and provide better feedback when stats change. I also did not quite understand what the wheels being red means? Maybe pop an indicator about that somewhere in there.
I understand the premise (from the previous comment) but I think the theme's integration could have been a bit stronger.
All in all, a fun experience, good job!
