Each moon contains four levels incorporating several gameplay modes and perspectives:
- Level 1 is a first-person 3D space flight simulation, as the player pilots a ship over the moon's surface looking for the entrance to a cave.
- Level 2 is a side-view scrolling shooter in which the player explores the cave in search of bombs.
- Level 3 is similar to level 2, except it takes place underwater.
- Level 4 is the final one; it is a top-down grid-based maze shooter, as the player tries to plant the bombs and escape before they explode.
