im stuck after i got U i dont know what else to do like i know where H is but i cant get to it because i fall past it and i cant figure out how to get H or what to do next (please help
Same here. The start mechanic doesn't work in the H room [new version after speedrun vid 3mo ago], or any room around it as far as I can see. Nor are there any activated speech boxes.
Also it's possible to lose letters in the room below H, they float to the ceiling if shot left.
