Really like the art in this game. I would suggest that the puzzles have more to do with changing the size (right now it's just find the item, maybe change your size to get it, adjust the item size and insert it somewhere). Also an interaction popup would be useful, so you know which objects are pickable and which are in you range. Otherwise that's a solid game.
PS modify the embed size, so that unity's fullscreen button is visible and hide the itch.ios one. Right now it doesn't work.
