バグ！

Bug! is a 1995 platform game developed by Realtime Associates and published by Sega for the Sega Saturn. It was also ported to Windows 3.1x and Windows 95 in 1996 by Beam Software. The game is one of the earliest examples of 3D platforming, as well as one of the first platform games released on the Saturn. Character movement is restricted to a track, unlike many games in the genre that allow for unrestricted movement in all directions.
