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 Super Smash Bros. Melee was based on Helmet while Flat Zone 2 from Super Smash Bros. Brawl was based on multiple Game & Watch games like Fire and Chef. Instead, Flat Zone + is very reminiscent to the Ω form of Flat Zone 2 and Flat Zone X from, respectively, that connects to the border of the stage.

Music

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 baggage 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  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.
