Welcome to South Hell

You wake in a locked school basement and have to escape. Pry five boards off the stairs with the crowbar, find four keys in school lockers, turn the four locks on the glowing basement exit door, and press E Escape when the door says it is open.

The tutorial card HE HUNTS YOU names Cartman. A catch costs one of your three lives and drops any key you are carrying. Ike is a separate flashlight threat. The tutorial says not to shine your light on Ike.

A recorded Medium run found Blue in the 4TH GRADE green lockers, Yellow in a lower LOCKER ROOM locker, Red just outside the NURSE room, and Green in the COMPUTER LAB. That run is a worked example. The objective only counts keys as 0/4 and does not name a room for each color, so search lockers if a familiar room is empty.

Yes. A recorded solo run finishes the same four-key door and E Escape. A group of up to six can split the search, but the server size of 24 is not the same thing as your bus group.

The experience description asks players to use the mailbox in the lobby for bugs and ideas. The same description says the game just released and bugs are still being fixed.
