I’m guessing that the red lines and arcs you see are future moves the AI is choosing from. Moves could be selected by ranking their potential outcomes. A move’s score increases for positive outcomes like landing on solid ground, squashing an enemy, moving closer to the goal line, or headbutting a |?| box. The score decreases for negative outcomes like being killed by an enemy or falling in a pit.
