Man, I haven't even played it yet but I already gave it a 30/10 rating. (:
i can't beat it? i pressed the button after the vent but now i have no idea what to do. pretty decent mod
Psst, just leave and the "secret" door at the end of the hallway will open.
My suggestion: add a few checkpoints. I liked it, had a nice atmosphere. Keep up the good work! :)
