Ahaha. This is so amazing dude. This is the real deal! Yeah it has some bugs, but I'm surprised the switch puzzle actually resets when you get out of the room and re-enter.
Seriously though, this is very, very good. I really hope you get to finish this, get all the help you need and keep this level of quality. It really kicks the drek that is the indie-horror scene in the ass.
Consider already one sale, and a bit of a support from me. :)
