I put out a build that capitalizes on the creepiness if you get out of bounds, I hope. It should also let the player continue playing, if they wish. Out of curiosity, what build were you playing on (webGL, linux, etc.) and do you remember what you were doing when you fell out of bounds?
I was playing the webGL version (Firefox, Windows7). I remember distinctly that I was walking towards a door because of how the light fell away from me. Maybe I'll try one of the other builds later. Tomorrow I'll be playing these games from a different computer, so maybe I'll download then, and see what happens. Can't wait to see this new build :)
