I've tried optimizing it quite a bit. Does the game run smoothly despite how hot the phone gets? Which device are you using? And which parts does the game lag at?
The game does run smoothly, yes. Actually, I just downloaded the latest update, and my phone seems to be handling it better! I don't feel comfortable sharing the specs, but the game does still lag a bit when dealing with Stella's jiggle physics. It seems like she has two pairs of boobs..?
