Like in source game, there are various Game & Watch characters who make appearances at periodic time intervals, such as the oil panic character who spills the contents of its barrel across the stage floor and the manhole characters who both hang from the preexisting background platforms and occasionally 'fill in' the gaps between said platforms there are also the various tools that rain down upon the stage, though they can't cause any damage to the combatants.

Melee, complete with areas at the top and sides of the stage where the Game & Watch console is layered in the foreground, which obscures the view of combatants that venture into them. Medrops' Flatzone is a custom sprited stage that mimics its appearance in Super Smash Bros. The stage's camera is configured to try and keep combatants as central as possible, which is achieved horizontally by ramping up the tension value to 120 so that the camera moves if a combatant tries to move forward beyond the centre, and achieved vertically by setting the zoffset to a value that significantly raises the stage floor and floortension parameter to zero so that the camera will scroll up with any vertical character movement. Though the stage would appear to be a completely static image made up of the two sprites, there is actually a manhole platform that eventually starts appearing and disappearing between the static platform and the house on the right, but because it takes three minutes for said platform to first appear, it is unlikely to ever show up in a typical match. Melee, which has then been split into two separate sprites so as to achieve the source game's effect of having the console sections of the stage layered in the foreground naturally, this will obscure characters who walk into these sections on the top and side areas of the stage, the latter of which can grant both situational advantages and disadvantages to thinner characters. Superflat World: Flat Zone appears to be a scaled up and colour-lossy screenshot of the Flat Zone stage from Super Smash Bros.
