This is a really fun demo, looking forward to more!
One weird glitch I found was that, near the end of the demo while I was on my way to retry the boss, Gedda walked right without stopping. He walked past the boss room without triggering the boss and into the end of the demo. Pressing escape stopped him, but if I pressed left or right again, he'd continue moving in that direction.
In case anyone else experiences this problem, returning to the title screen fixed the issue.
