Weirdly can't a direct link to this game on google, but the first result is "games similar to this".
I liked to mess around with the game a bit. I like how the bat can grow either super muscular or super fat depending on your stats!
Kinda wish there was more art assets in this game, but I understand why it's difficult to accomplish.
Also, can I suggest another mode? Realism mode. Basically doesn't allow you to become 100 meters big and 500000kg heavy lol. So harder progress and capped stats maybe. These games can be fun until you become so gargantuan you have trouble imagining how you even walk through a street without collapsing the pavement.
