It looks great. Although the sounds were a bit too unpleasant. The first time I tried it, I got so close to the symbol on the wall that I walked right through it and ran into the Ripper. On my second try, I managed to find the skulls but didn't know how to open the door; when I tried to go back, the Ripper was there for the first time, and there was nothing else I could do to escape hahaha.
Great premise, congratulations!
