I should post a link to download the old Scarey Game (Remake). I liked it better than Murder Mansion and there were some awesome mechanics in it. (Lots of trapmaking ability)
There's 1 or 2 murderers. They each start with psycho outfits they can put on or off at will, and come with their own knife. Items are not used by clicking on people, you just click on the item in your hud(This works way better for attacking in a byond game than the annoying click the mob mechanics). The game ends when there's just psychos or just innocents left. If an innocent kills an innocent, he dies too, so you need to be certain that if you're going to retaliate against the psycho, you're actually attacking the psycho.
The traps were awesome. You can make oil slicks which cause you to move quickly in a certain direction(Always fun to slick them into a deadly obstacle, like a fireplace). Spring pads, glue, wirecutters(For exposing electrical wires), moveable furniture(Barricade yourself in a room if you like). Lots of hidden secrets, and one item that can actually revive a person(it's tough to get to and get back from alive).
I'll look for it on my computer(I know I have the hosting files somewhere), and post it here.
