I found a bug: if you step on a rotating mover, then move one extra space, then undo one move, the rotation of the mover also gets undone when it shouldn't do. This happened on Season 5, Episode 5.
Have about 50% completion so far, and the game is really fun! One aspect that I have found frustrating though is not being able to undo moves any more if you game over, and having to restart the level completely instead.
