Well, there are some problems with this. Firstly, it would require some effort to determine a clear start- and endpoint to the run, which might not be worth the effort as there aren't that many people interested in speedrunning this game atm. Secondly, also related to the popularity of steep speedrunning, there isn't much point in adding this kind of categories, since it will just clutter the leaderboard page without much activity. At this point we just prefer to keep the page restricted to 'bigger' main categories. Feel free to leave more suggestions though!
