Keystone Kapers is an action-packed game where you play as Officer Keystone Kelly, tasked with capturing notorious thief Harry Hooligan. Trapped in a four-story mall, Harry is making a break for the exit at the top, and it's up to you to catch him. To do so, you'll need to use either the escalators at the end of each floor or the elevator in the middle to navigate between levels. The decision is crucial, as the escalators may be further away but move slowly, while the elevator accelerates faster, allowing Harry to stay one step ahead if you don't catch him quickly enough.
The gameplay is fast-paced and challenging, with Harry hurling shopping carts, bouncing balls, biplanes, and other obstacles at you in an attempt to slow you down. If you get hit, you'll be sent back to the beginning of the level. As levels progress, Harry's speed increases, and more objects are thrown your way, forcing you to dodge and jump to stay ahead. With Keystone Kapers, will you be able to catch Harry Hooligan before he reaches the exit, or will you find yourself retracing your steps?
