As you have started a thread already, I'll add mine here too:

- On the very first level, the copy needs an additional space ("canonly")
- The pushable boxes sometimes get stuck. I had to push them from the other direction first to be able to push them in the intended direction after
- On the 5th level (where the text says "I didn't mean to leave these here"), after you pick up the "down" action, I couldn't actually fall down and got stuck, had to fully restart. After that, I've realized I should have picked up the other direction first, as that was the intended route. Not a bug per se, a restart level button would have solved the problem here.
