it is widely considered Imagic's answer to Nintendo's Donkey Kong, featuring a similar "climb the building to save the girl" mechanic.
The player controls Bashful Buford, who must scale the Mutton Building to rescue Tiny Mabel from the giant Horrible Hank. Gameplay involves jumping over obstacles like bats, rats, and boulders while waiting for windows to open for climbing. Collecting hearts dropped by Mabel grants temporary invincibility. Upon reaching the top, Buford defeats Hank, causing the giant to fall, after which the game restarts at a faster, more difficult pace.
