Wow! Player/AI redesigns, gravity highlights, talking, AI talking, and player/AI arrows, this is one update! How to play: WASD/Arrow keys to move and jump. T to talk. The AIs move, jump and talk on their own. Blue AI tries to follow you. Yellow AI just wanders indefinitely. Red is not AI, it is the player. It is the only character you can control.
Thanks to griffpatch_tutor for the OG game.
