Spinmaster

Spinmaster is a platform arcade game developed and published by Data East in 1993. The story follows the main character Johnny and his buddy Tom, who fight their way through the minions of the mad scientist Dr. De Playne to rescue Johnny's girlfriend Mary and find a hidden treasure. Both playable characters are armed with yo-yos, but can also upgrade to other weapons (such as throwing stars, icicle daggers and guided missiles) to defeat all enemies and help them open treasure chests.
