Roboto is a traditional side-scrolling platformer. The player is a robot with a hoverboard. The goal is to save a robot girl, but there's no real story to speak of. There are three worlds with 10 levels each, and players are given a bronze, silver, or gold medal depending on how well they complete each level. The game features a light upgrade system - players use the gears collected in each level to purchase a handful of better weapons and two improved armors.
