What a fantastic puzzle game. I thought they were really well done. The sound pinging was really cool and I liked that you actually had to switch between the sound and visual. Very cool! I think the movement was a little too difficult. I would've liked to be able to move in the air. Like just walking up the steps on that last level was really difficult because I just kept running into a step and then jumping and not being able to move. But that's the only complaint. Really well done :)
