I enjoyed the concept, I was pleasantly surprised by how fun it was. I really enjoyed level 5 & 7. I also appreciated the hints for whether you were in the right direction with the overlapping. My only two nits is that it would be nice if there was more feedback upon submitting a level successfully, and I was a bit confused with level 6 (felt like the 11'oClock should have been first, maybe I was misreading the clock). Great job!
