I generally enjoyed this game, though there were definitely points that nearly caused me to stop playing because they were just a little TOO tough. Nothing was impossible, but some of the windows of success are just a little too small for a casual player who is coming into the game without prior knowledge of the puzzle. I think with a little more feedback from players (maybe watching a few streams of the game), you'll be able to identify the choke points and really refine this into something even more awesome!
