Literally the scariest game I've ever made, reshared after 3 years :D You look around at the lonely concrete walls, chilled by the silence. And yet, it would seem you're not the only one trapped here.
"Cheats" (This game is hard...): Press 'M' to show the map. Hold Space to run Modifiers: Press "q" to tunnel through walls. When used, the game automatically enters hard mode.
