Really cool idea, I did end up getting stuck at the start of the 3rd level where I couldn't move far enough to change the pit I was in.

Assuming this is the sliding-block-puzzle room (the one with the block in it)... You just fall right through! There are multiple pits "underneath" which lead back into that same room from a different angle. You use your own gravity to move the block to the button! I suspect I didn't exactly telegraph this process well enough, though...
Generally, hopefully, you can't get stuck. I checked all over the place for weird softlocks and wasn't happy with the layouts until I couldn't find any more. Falling into a pit is almost always progress to a checkpoint!
I just tried it again, the block puzzle was great! I was 'stuck' with the exit from the yellow level in the floor and the blue level npc on the right-hand wall. I thought I couldn't get back into the yellow level after leaving it because I kept walking over the gap. Turns out I was mistaken and just didn't try hard enough so I was able to go back and reset the orientation.
