This thread is for requesting new categories to be added. My request:

I am interested in speedrunning Red Ball 4 Mobile, but playing through all 75 levels can take a long time, especially as a beginner. Can there be an Any% and 100% category for each individual world? (The format of the main page would probably then look better as a table, like Cut the Rope's page.)

True

Totally agree with this post! It's sad it hasn't got any replies in a year tho

Check the level leaderboards, there's already a category for each world there.
