After about 20 levels, I got more interested in skipping to the end for free. Poking around, it turns out that the game state is stored in browser local storage and fairly easy to reverse engineer (lesson for the motivated reader). Suffice to say with a few edits I was able to skip to the end and get to level 118. Still only 4 slices :)
