Thanks for the comment. At the moment the only reward is getting a compliment when finishing the level with few enough steps. But you're right, it would be nice to save best results and have ratings or medals based on how well you do. While I don't mind players cheesing their way to the solution on their first playthrough I would like to encourage players to try to optimize their runs. That's where most of the fun is for me at least. I'll keep this in mind.
