The core game loop for release is finished. Basically, there are concentric circles around spawn which have something that prevent you from passing unless you have the correct โโโโโ.
Additionally, entities and general difficulty increases the farther you are from spawn.

One new item is the gas mask which can be acquired โโโโโโโโโโ for โโโโโโโ. It comes with a nice screen effect and muffled sound filters so it feels like you are wearing a mask.
Overall the game at some points felt like playing SCP.

Stay tuned!
