Flat Zone +

Flat Zone+ is a starter stage in Super Smash Flash 2 that takes place inside a giant Game & Watch unit and it comprises of elements from several different Game & Watch games. It serves as the home stage for.

Layout
Unlike the stages that have carried the name of Flat Zone, Flat Zone+ is not devotedly based on one Game & Watch game as its main form, like how Flat Zone from Melee was devotedly based on Helmet while Flat Zone 2 from Brawl was based on Fire (transitioning to other Game & Watch games), but rather, amalgamates the games Manhole and Turtle Bridge in one form.

Most of the upper left side of the stage is covered by numerous pass-through platforms, below that are two holes filled by the Manhole man, the lower right portion has a large body of water where a swimming turtle can be used as a platform, right above is a hard platform very reminiscent to the Ω form of Flat Zone 2 and Flat Zone X from Super Smash Bros. for Nintendo 3DS and Wii U, respectively, that connects to the border of the stage.

Music

 * The main music track is titled Flat Zone 2, from the Super Smash Bros. Brawl soundtrack.

Origin
The left side of the stage is based on Manhole. In the original game, a man has to navigate a pair of sewer lines, each with two gaps, holding a single manhole cover above himself, to prevent a line of pedestrians from stepping into the gaps and falling down into the sewer below.

The right side of the stage is based on Turtle Bridge. In the original game, a tourist had to deliver their baggages across a river, using turtles as stepping stones. The turtles would occasionally dive for fish, putting the tourist in danger of being dunked into the river if he is standing on it at the time.

The lower half of the stage is based on the original Game & Watch units, while the upper half of the stage is based on the previous Flat Zone stages in the Super Smash Bros. series. In the Manhole section, in place of the upper bridge is a series of LCD platforms, as they appeared in both Flat Zone in Melee and Flat Zone 2 in Brawl. To the right of those is an LCD brick structure taken from the Ω forms of Flat Zone 2 and Flat Zone X in 3DS and Wii U.
