Nice concept. Reminds me of the old circular puzzles I had on my geometry box. But the controlling the rotation is very hard. The puzzle's level design is such that I need to do full 180 flip instantly at the right moment which is very difficult with the set rotation speed. It would be nice if you could tweak the rotation mechanics (maybe add button controls for it too) and add some simple beginner levels to get players into the groove. It'll be a fun game with a lit bit more work. Keep it up!
