Bug!

Bug! is an arcade platform game developed by Realtime Associates and published by Sega. Released in 1995 for PC (Microsoft Windows) and Sega Saturn, it combines traditional side-scrolling adventure gameplay with three-dimensional level design.

Players guide Bug through large stages, jumping on enemies and collecting power-ups. Its distinctive movement system lets Bug travel sideways up vertical surfaces and even move upside down. The game’s environments range from bright, grassy areas to deep red desert levels, with each set of stages offering its own visual style.
