Really great concept! Just difficult enough that I struggled at first, but once you get it, the puzzles are really engaging.

I had difficulties getting the harder puzzle ideas I had in there whilst giving a smooth difficulty curve. I think I did okay enough, but looking back, I would swap around a few of the levels and better explain the hourglass buttons, since I did notice those were large issues in people getting into the game.
