This is a very serious game that taught me to appreciate my ability to walk in straight lines without spinning. I can definitely say that it has changed my life for the better.
Seriously, though, this game is amazing! Very nice and distinctive visual presentation, I liked the combination of photorealistic environment textures and flat colored characters. Puzzles are deviously hard for me, since I've always had trouble with timing, but I appreciate the simplicity of design and variety of challenges.
Walkable cities for everybody!
