The Falling Platform is a gimmick in the classic Mega Man series, introduced in Mega Man 2. It is a platform suspended in the air that drops to the ground if too much weight is put on it.
The original Make a Good Mega Man Level included two variants of Falling Platform; the Falling Platforms found in Bubble Man's stage from the aforementioned Mega Man 2, and the Falling Platforms found in Gyro Man's stage from Mega Man 5. Falling Platforms appeared in the entries Napalm Forest and Caves, Maze of Death, Spiky Meltdown, and Glass Man, as well as the Wily stages Be the Bigger Person1, Hall of Fame, and Flashback Database. Glass Man uses a custom variant.
Both the Mega Man 2 and Mega Man 5 Falling Platforms returned in Make a Good Mega Man Level 2, where they appeared in 9 entries, as well as the Wily stages Unobtainium Mine and Reality Core, the Tier X stages Goblins n' Ghasts, Mario Land, and Deep Thoughts, the Pit of Pits sub-levels "Epic Wrap Battle", "Glass Man?", "Ground Eater", "Hot Mess", "Overwater Atomsphere", and "Spiky Meltdown?", and Null and Void. They also appeared in the Make a Good Mega Man Level 3 Judge Application Level Space Crusade. Goblins n' Ghasts, Mario Land, and Space Crusade have custom variants of Falling Platforms, and the custom Glass Man falling platforms return in "Glass Man?". In Make a Good Mega Man Level: Episode Zero, Falling Platforms were used in 8 stages, with the Goblins n' Ghasts variant making a return.
Falling Platforms will simply float in the air at first. When Mega Man lands on one, it will fall shortly after. The Mega Man 2 and Mega Man 5 Falling Platforms take about the same amount of time before they fall. Glass Man platforms take longer to fall, while Mario Land platforms take less time to fall.
