Super Mario VR-32

Super Mario VR-32 is a 3D platformer game released for the  Virtual Boy in 1996 for Japan and North America and in 1997 for Europe and Australia.

Super Mario VR-32 is the first Virtual Boy title to be composed primarily of true 3D polygons as opposed to only two-dimensional sprites. The game is also the first Virtual Boy title to be released for Europe and Australia.

Gameplay
Super Mario VR-32 is a platformer video game and the first in the Super Mario series to feature three-dimensional gameplay. The player explores large open 3D worlds with degrees of freedom through all three axes in one space, and emphasizes exploration within these vast worlds, which require the player to complete various missions in addition to the occasional linear obstacle courses (as in traditional platform games). It preserves many gameplay elements and characters of earlier Mario games as well as the visual style.
