It would have been cool if there was more visual feedback (an animation instead of flipping instantly, maybe?) on the rotation. I kept forgetting which direction came next. And maybe left/right click could rotate in different directions? It was sometimes tricky because I wanted to reflect it one way and then almost instantly reflect it with the rotation three clicks away. Though maybe that's an intentional part of the difficulty?
But yeah, that was fun. I always like games where you reflect a thing.
