Space Ace is an interactive adventure game adapted from the classic animated film of the same name by Don Bluth Studios. Players take on the role of space hero Ace to stop the evil commander Borf, who plans to use the "Infanto Ray" to turn humans into babies and invade Earth. As Ace approaches Borf's lair, he is hit by the ray and turned into a child, while his companion Kimberly is kidnapped by Borf. Players must control Ace, dodge enemy attacks, jump over obstacles, find and destroy the ray gun, rescue Kimberly, and save Earth. The game uses interactive video, letting players choose actions at key story moments to shape the plot. It is quite challenging, testing players' reaction speed and operating skills.
