Nice dude. Good job! I would suggest you, in my humble knowledge, for you input in new version some trap in this scp-1499. That report story you know? I would love fell in this trip(laughing). Image on: "Man, I get this mask, maybe I will use that later..." hahahaha So I would fell in the scp-1499 pocket dimension, and I would need flee and sneak to portal to "take off" the mask and return in same mask room but avoiding yet the scp-106. Think about it. Thanks to available this awesome project and I wish for you a great successful.
