mechanic: G-67 will spawn with an error sound and will spawn in the current room. Shortly after, he will turn green with text over his face saying go, which you have to get to 3 rooms ahead. When he turns red and says hide, do what he says or shortly after he will instantly kill you. When he says slow down, slow down or he will slowly damage you. If you get to 3 rooms ahead, he will despawn. Sounds and costumes are inside the project code.
