This movie improves the first rat on the second stage by passing over the camera borders with enough momentum on the 2nd player to "flow" through it instead of bumping it. This saves 15 frames.
No other places seems to be improvable (rat spawns are timered and game end glitch routine requires BUDR, AR and enough (3) input reset (ABSTUDLR which allows us to input two other inputs).
For more detailed informations, take look at at the previously submitted movie submission text
Feos added as co-author since I've used his lua scripts to optimize movements and check a few other thousands of possible game end glitch tests.
GoddessMaria: Excellent work on improving what was considered to be pretty tight already! Audience reaction was positive and entertainment value was high as well!
Accepting as an improvement to the published movie.
