This page is a list of the beta elements in Game & Watch Returns!.
The game was originally called "Game & Watch 3DS" but was changed for unknown reasons.
The game was originally restricted to 2D mode. If this was kept present in the final version, it would have been the first 3DS game to do this.
If the game kept the 2D Restriction, Nintendo would have made a DS version of the game as well as the 3DS version.
