The Gap is the third level of the Light World of The Forest in Super Meat Boy.
This level has near-symmetrical geometry with a large gap in the middle, a scenario designed to introduce sprinting to the player, requiring it to get over the gap.
Strategy[]
Simply put sprint and jump to the other side of the gap to reach Bandage Girl. This is the first level that poses any real threat of death, as falling into the gap will kill Meat Boy. There are also exposed sawblades at the top of the level, but they are still likely meant for decoration, even if they are hazardous.
Despite apparently being essential, completing the level without sprinting is possible. To do this, the player must climb up the wall and jump over to the other side.
