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 █████.
Additionally, entities and general difficulty increases the farther you are from spawn.

One new item is the gas mask which can be acquired ██████████ for ███████. 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!
