Murino

Murino is an anomalous zone where the height of buildings exceeds human comprehension. The laws of physics, logic, and morality are violated here. No one remains here, and the density of mutants per square meter depends on the floor height.
In this game, you play as a courier who needs to deliver an order to Murino, located on a very high floor, in apartment 69 (the full apartment number is 52.69).
