Despite the puzzles being fairly simple I still managed to be surprised! I was kind of annoyed by the second tree branch on the tree house steps since I had to swerve around it but it wasn't that bad. I also loved the ending, very neat use of the concept. My only other issue is I wish some of the puzzles, like the mushroom and the snowglobe were solvable without the hint. I really like the way the mushroom puzzle turned out though!
