Very nice game! only feedback is to change the background a bit (basically just art) cuz every level except the first feels the same. would be nice if there were different thematic parts of the muntain (i understand that it was only 4 days, just saying incase u continue working on it)
also i only did like 7 levels so maybe u do have more and i just didnt see it, in that case mb
level design and puzzles are spot on tho!
