Watch NPCs Evolve
Watch NPCs in a glass box try to learn to walk to the end, and hangout with friends! NPCs have a 25% chance of mutating when spawned, and at the end of every generation (new generation spawns when all NPCs win) every NPC has their stats set to the stats of the NPC who got to the end fastest.
WARNING: These are not real players, they are just randomly moving NPCs that will evolve. If one stares at you, do not stare back. It is luring you in.
