Loved this one! You are a genius!
The first room had stumped me for ages!

If I wouldn't remember something I would have stared at it for hundred years -- ya stinker!
Then, I was scared pushing that boulder to the right, I was relieved when I pushed it and saw that this conveyor stopped!
Although, the fake wall was clearly visible at the end, I got so excited that I forgot to get the coin in it -- had to pass the boulder three times instead of one!
Great puzzle, with a difficult start and with a surprising end.
