Very fun! I love the unique take how tools are used. I also enjoy the exploration required to progress the game. Finally, the game flows well without too much dialogue.
The game is quite polished so my only complaints are nitpicks. First, if you wanted to continue improving the game, I would definitely watch some people do a full play-through. I was unable to finish the game due to getting stuck on where to go next, and I imagine that it could happen to others as well. Further, there are a couple of sections that are overly difficult. I believe that watching player's reactions would help smooth this out.
Oh, and the sound effects might need a little better mixing. Some are jarringly loud.
Otherwise, fantastic job! I had a great time playing the game.
