Interesting concept, but not the best execution. The simple fact is, a puzzle should only have one solution. I ran into several puzzles with more than one solution, which shouldn't happen. This type of puzzle has been done many times and much better.
I like the idea of the rotating pieces, but I think that actually limits the puzzles. It gives me so many more options to solve the puzzle.
Overall, I enjoyed the game, but it has too many issues in my opinion.
