Really cute game! Liked all the puzzles and the art especially too!
I found a few bugs during my playthrough:
One regarding using things like ladders etc while holding an object which glitches the character around and let the item drop.
Also if you drop an item onto a wall right in front of you and the item drops on you it can glitch you through the ground:
Another thing is that the white buttons you "cant hold down". you can if you timestop and anchor it. it may not highlight as selectable but it still lets it freeze in time. (Even though holding them down doesnt really do anything gameplay wise since it works more like a switch)
