Most of game consists of a side-scrolling arcade platformer, in which the player controls Lucy and Sunny. Lucy can run and perform some tasks, like operating lifts and manipulating some devices. Sunny, meanwhile, can fly and can access some hard to reach areas, but he lacks hands, and thus cannot do some of the things Lucy can. He can also help Lucy by carrying her safely down from high places. Traveling through the corridors of the ship, the little duo will encounter various patrolling robots, which will try to catch them. The different robots have varying abilities, which the player must pay attention to, in order to help the protagonists avoid capture. Most of the robots are able to catch Lucy, while Sunny has less to worry about, as there are fewer that can catch him. The player must be clever in managing the two heroes' abilities and vulnerabilities in order to help them on their quest.
