I tend to like single-puzzle games, so I had high hopes for this one. The concept is very good: take a classic puzzle and twist it by making the standard solution impossible.The game itself is a bit underimplemented, but the strong concept makes up for that in part. I had a good time playing it, but unfortunately I ended up winning easily because of a bug. I didn't even realize it was a bug, so I headed straight for the hints and ended up surprised and somewhat disappointed. Overall a nice effort, but wait for a post-comp release.
