This is shaping up really nicely. I wish you had a bit more time to make the cylinders into ghost. I think removing the risk of falling off the edges made this so much more enjoyable. The only thing I noticed was that if you die the game restarts everything start moving (i.e. the ball started falling in the last input direction and the ghost started moving towards you) but don't have control over the player and a couple of time I died as a result because the ghost were right on top of me when the controls kicked back in. I think that the player should have a few seconds of invisible frames to start moving before and ghost should start to peruse the player. I also think the game should auto pause if it stops getting input from the phone. I was playing so long that my phone cut off and I got caught by a ghost trying to cut it back on.
