Disclosure the creator let me try the game for free to give my thoughts  and here they are: everything in the game works great I wish the balling music played as you're going through the levels but that's a minor complaint this game is for advanced puzzle people though or at least more advanced than myself all my brain cells were popping and I could only get to level 18 I would definitely recommend if you like puzzles and a challenge you'll definitely get your moneys worth if you're that skilled but if you want to see how hard the puzzles get my video here (I did not complete the game 18 was my max):
