Summary
One night, the sinister Thump sneaks into the castle of the Gadget Kingdom and makes off with the Gadget King’s precious gem. The following morning, the king awakens to discover his gem has been taken. He then calls upon Bop and Bump to recover the stolen treasure from Thump.
The gameplay features six levels set in the skies and seas: Gadget Bay, Zeppelin Attack, The Lost City, Sub Attack, The Crystal Lake, and Thump’s World. While the game scrolls continuously through each stage, players are free to maneuver in any direction on the screen. Bop and Bump are armed with a spring-loaded glove that allows them to punch in any direction—up, down, left, or right—to battle enemies.
When enemies are defeated, they drop coins. Additional coins can be found inside chests scattered throughout the levels. These coins can be used at a shop to buy power-ups and enhancements.
The game also includes bonus stages where the goal is to collect all the chests within a time limit.
