Nice idea! It's a little difficult initially but you learn fast to play. I found the win of a level not very exciting so it seems that it is not so important to overcome the level but that the importance is in how to overcome it. Great job!
Thank you for the feedback. You are right, I wanted the player to focus on the process of completing a level (like a puzzle) more than anything else. But, perhaps I could make the level completion a more exciting 'event' too.
