Thank you!
I def agree that some of the timing esp later on was probably a bit too tight, I kind of lost the slower puzzle-y vibe a bit over the course of the game as I was rushing to just get some kind of level out to fill out the game - with more time for refinement there would've probably been more slower paced puzzle rooms, and a bit more leeway for the rooms that do require tight execution.
The bug with the block not fitting into its hole is a bit concerning, all the linear blocks are supposed to move on fixed paths and not be pushed by anything else so there shouldn't be any way for them to get misaligned like that. Do you remember which room and platform it was that happened with?
