Seems like the game isn't in a ready state yet. No sound, no apparent way to interact with the one visible object aside from the character. Walking to the right leads to you falling off a platform and getting stuck off screen. The only keys that seem to do anything aside from WASD to move and space to jump were tab, caps lock, and shift, which only opened slow unskippable text boxes that implied the powers associated with them were not unlocked yet.
