Quite a unique and unusual offering! Not sure how you came up with the idea but it works! The gravity option is my favourite :D Not sure what the submission page did or was supposed to do though? Music was nice, and I liked the use of assets.
The submissions page has a solution to the puzzle, but there is a known bug with it at the moment so that may have affected your experience. I'd recommend trying again if this is the case!! Thanks for the kind words as well.
