Had fun with this one, and I usually don't with gravity-switch platformers, but the precision leniency that comes naturally from your specific implementation was a nice surprise. Being able to switch gravity directions by simply jumping against a surface is great. I'm not sure if there was supposed to be music, but I didn't encounter any unfortunately, and the sound effects are a little tough on the ears unless you really lower the volume. Still, good game with fun puzzles to navigate!
