I though the mechanic would have very limited possibilities but you manged to use it in quite a few unique ways, which was neat.
But it can be confusing on where the players is supposed to go (lvl 10 for example, there is a seemingly random area to the right?)
Level 8 can be won by just going over the top, not sure if this is intended.
It can be kind of annoying to keep doing the same "setup" for the puzzle part of a level. In level 12 for example, the player has to break the glass and move the boxes each time they want to give the second part with the fan a try. I really only found this annoying for level 12 though.
Apart from these things I really enjoyed the game and hope to see more!
