I'll recommend you working a little bit on it, adding some kind of personalization for the balls and a points system based on how fast can you complete the levels. That combined with some extra gameplay mechanics and some extra levels could be awesome and you could even try to sell it on steam ^^
Or even a "Build your level and share it for others to play" option would be cool too. Even more if the game had a rating system that everyone could rate the personal levels and you can search/filter them easily.
