In the last stage of the previous TAS, at the ladder above a mine, the previous authors chose to climb the ladder. The time to climb the ladder minus the distance difference between the two characters is 16. So I think it can save 16 frames to let 2P step on the mine.
This TAS is easy to do, and I only changed the last stage, the final time is only 16 frames faster. So I put my name after the two previous authors.
Replace the file with a 4 frames quickly. http://tasvideos.org/userfiles/info/58093784426114001
The total improvement is 20 frames.
Masterjun: Replaced file with 4 frame improvement. And claiming for judging.
