I have a few questions about speedrunning this game. I recently got the iOS version of this game which comes with the first three levels free. You have to pay to play the other levels. I was wondering if it would be possible to create leaderboards for individual levels as well as a category for the first three levels. I was also wondering if there is any difference between the iOS version and the PC version of the game. Thanks!

I think you just do every level. There isn't really a route, because there are no levels you can skip over.
