Osta We Are So Dead PC

A co-op seance communications game where one of you died first, and only you can see what's killing the others.
Your only voice is a Ouija board your friends keep misreading.
Guide them through a haunted house and banish the demon before sunrise.
Can you banish the demon on each floor and reach the bottom of the house?
2-6 players. Brain required.

• One of you starts dead. Each game, one player becomes the ghost — able to see the demon, the dangers, and the way out, but unable to be heard by the living. Ghosts can hear the living, and each other (ghosts can hear other players, but cannot be heard by non-ghosts.)
  As the ghost, you can see everything — the thing hunting the others, where it's safe, the way out before sunrise. The catch: you can't be heard by the living, you can't touch anything, and your only voice is some flickering lights and a seance board that your friends half-believe is even you.

• The Ouija board is one of the only voices of the dead. The ghost moves the planchette to point, answer yes or no, or slowly spell things out — and the living will attempt to question them and read it under pressure.

• A different demon every time. Its rules are hidden and change each session. Only the dead find out what they are, when they strike, and where. The ghosts can see the danger before it hits. They must communicate it with the living and help them banish the demon so they can leave the house before sunrise.

• Gather the relics, one trip at a time. The ghosts search the house for what the ritual needs, then attempt to communicate it to the living, who will then be carrying each piece back while the ghost steers them around what they can't see and what will kill them. Only the ghost can see what and where the relics are, and only the ghost can see the dangers.

• You're a ghost. Do ghost things. The ghosts can flicker lights, open and close doors, go through the living and they'll feel it, and as a last resort: scream, loudly -- and if you're all silent enough, you may just hear it. The seance board is not the only way to communicate, but is the only stable way to get full words across to the living.

• Banish the demon by name. Winning means spelling out its true name — readable only to the dead once all the relics are collected, then the living must spell it back — so you can banish the demon and get everyone out before sunrise. For example, you and your friends will be spelling ULALULA on the board like crazy people to win the game (and pray that you read it right from the ghost player in the first place!).

• Dying lets you help. Players the demon takes join the dead, adding another voice to the seance, and more help at finding the relics and warning players of the dangers. 

• Nine floors down. The house is bigger underneath. Banish the demon to unlock the next floor, each further from sunrise than the last, and each one holding something the floor above it didn't. Can you and your friends reach the bottom of the house and beat floor 9?

• 2-6 players online co-op.
  You spell H-E-L-P. They read HELL and cheer. Someone gets dragged into the dark. To survive the night, the living will have to haul the right relics back to the seance board and spell out the demon's true name to banish it — and the dead are the only ones who can read that name.

It only takes one friend who listens to the dead to save everyone. You do not have that friend.
