If you get a keycard, press space on SCP-173's card reader to open the door. If you get stuck, press the "h" key and type "0,0" to reset your position. There are other cheats you can do to, like getting an omni keycard, or a specific combination of numbers to summon scp 066 for no reason! edit: if you get stuck, when you blink, move the direction you need to go before the black screen is done showing.
this is a beta remember.
