To my surprise, there are only 2 speedrun for the entire game (and then any%). I decided, albeit crookedly, to record the first speedrun on 102%

There is at least 1 bug to reduce the time: when entering the level and the treasury, you can press the uppercut (that is, Up + Attack, and you need to hold Up). In the second level, I didn't do this for the treasury because the ceiling was too low, otherwise I just jump out, and there the combo will end
