This was made on august 20th :D there is multiplayer now, you can enable multiplayer in the world settings its fake multiplayer, the others are AI. I'm finding a lot of glitches so I'll fix them (the new mob can breed so don't keep the new mob in groups of 2+ or they will breed and over croud the game with kids :D)
