The new AI breaks when it uses the item "Mouth Clamps". It doesnt choose a pill. Or at least it doesnt after using a Test Kit on a green pill. (Dont know if the green pill was a kill or not).
Interesting, but due to how the ground can change into being more rigid I would change how the player moves and jumps because it can be difficult to move around in areas like that, although this gives the mountainous border a good way to stop players from moving past them.
