I went through twice. First time was just a no mod run to get the hang of things and the second was TASBot mode with the +200% speed clause. I gotta say, those robots definitely know what they're doing because it took me a lot longer to make it through the second time. With more haste, less speed, as they say.
Celeste famously mastered the feel of it's movement and physics system. What I like about the modifiers in this game is that they really prove how vastly different the game can feel with little tweaks here and there. Going through the platforming itself is kind of hard. Going through the platforming with all your schmooves shuffled up is REALLY hard.
Interesting exploration of this concept!
