The idea

Duncan demonstrates Jev steering Pac-Man at junctions using a JSON representation of the maze. The game remains responsible for movement, rendering and enforcing legal actions.

Inside the decision loop

01 / CONTEXT

Maze state + possible directions

02 / DECISION

Choose a direction

03 / ACTION

Advance the game

What to take from it

A game offers a clear boundary between a decision and its execution. The model does not need to decide every rendered frame; junctions provide natural decision points.

KEEP IN MIND

A smooth video is not a win-rate benchmark. Evaluate against a simple baseline over many maps and seeds before attributing strong planning ability to the model.
