I think timing should start when you click on your first level. There may be a reason to do it otherwise, and if so tell me, but I just think that's easier than guessing when Chubby will first move.

Is it because starting on first move allows people to wait for an optimal fish pattern and whatnot? Cuz if so, that's kind of ingenious, but also seems lame. Idk

In the Flash version's leaderboards timing started on first movement to keep it consistent with ILs. Today I made the timing the start the same as that version. Lots of games will start on full movement and you're not really in control any time before that. You could set your timer to start at -2.9 seconds then click the first level while starting it.

Any% and 100% in the Demo version will start when clicking on your first level, it was not possible to time from first movement because Chubby will outrun the black fade-in transition to not be visible at the start.
