Save for the few times the game forces you to use the boost (e.g. boss battles, Double Boost), most of the levels can be completed without boosting at all. Perhaps, after finding the areas that absolutely require boost, that could be a category, since it's actually quite a fun way of running stages.

Adding arbitrary categories at random is not something that is of our interest. Feel free to run the game however you want, but creating a category to a leaderboard that would probably be unused is not worthwhile for us to put together.

You should set up a sub-reddit or something for meme speedruns.
