I did a run of the workshop building tutorial, and I think it would be a fun category:

I've figured it out, now I just need to figure out how to beat Pete!!

How would I reset my progress for this game? And is it possible to do that without losing the progress from my main account?

Are there major differences in the game on different platforms? I want to start speedrunning on mobile, but it's a little disappointing that I would be competing with nobody.

To practice for the run or just for fun?
