Somebody asked me to upload a marathon run of this game, so here it is.
Marathon mode here goes beyond Lv20, at which lock delays continue to decrease. The lock delay decrease isn't as drastic as tetris.com client, and IRS/IHS with the lack of piece spawn delay makes the gameplay a lot less choppier.
However, marathon mode doesn't seem to have a speed cap as master mode of the same game does, or the speed cap is significantly farther away. Either way, the late-game marathon mode (Lv40+) is way harder than master mode's fastest speed, making this arguably the hardest mode in the game. Surviving as long as possible will be quite a challenge, wish the best of luck to anyone who wish to give this a shot.
