Cute models, although is there a way to add auto clicker? It gets tedious tapping the money button thousands of times. Could be interesting if exercise also rewards money, otherwise I'm not sure what the point of it is.
I only added it because I wanted to see overweight people exercising; I hadn't considered any game-related implications at all.
But you're right, it is a problem that exercise doesn't offer any in-game benefits.
I might fix it soon.
