Brilliant execution, the sound effects were very effective to give some early laughs. The puzzles were sequentially developing the core mechanics. The visual signaling was very clear, instructions came at a good pace. I really liked the naming of the levels having some tie to the solution.
I think the sound scape could do with a little more variation - despite the character's sounds being initially entertaining a longer play session could see that turn to monotony.
Overall, really good - I am not a puzzle gamer, but can totally see this is a good one.
