Pretty cool puzzle platformer; I can appreciate the puzzle design here! The music gives a nice "haunting" feel which I think follows the visual design pretty well!
Unfortunately I found I couldn't progress past a certain point (the first part the bat can't pass through) because I couldn't get the camera to consistently follow me. I can't tell if I wasn't intended to go to the other side because after respawning it did follow me, but then wouldn't follow me back to the left.
Great work for two days though!
