Jason follows his frog into an underground world and finds SOPHIA, a tank built for terrain that initially seems impossible. Side-view exploration puts its jump and cannon at the center of traversal, while leaving the vehicle lets Jason enter smaller spaces.

Important interiors shift to an overhead view, trading acrobatic driving for close navigation and gunfire. Defeating bosses grants upgrades that open new routes for the tank, encouraging you to remember barriers and return later. The vehicle feels powerful, but Jason outside it is vulnerable, making every exit a practical decision. The contrast between heavy machinery and a small person exploring unknown rooms gives the journey its unusual texture.
