I really like the puzzles and how they use tools that you unlock in previous levels to go through other levels. It makes it so you actually have to think about the things you are getting instead of being oh I do this I do that. If there was an expansion to the game, it would be interesting to implement rooms that require the use of multiple tools to get through it. The only issue I have is the lack of clarity with some tools. For example, when I got the bow, I had no idea how to use it and died. Otherwise, I think it was a well-designed and implemented game.
