As most others have already said, your GDD has a lot to it. Very cool to see as it shows how thought out everything was. The visuals complemented the horror aspect and I enjoyed exploring the unknowns of the map. Unfortunately, most attempts to get all the keys ended in (what I think) hitting myself with the little sparks from the lighter. Seems there is a lot to add to the prototype and it would be cool to see the missing features eventually added in! Great submission!
