This is a PSP adaptation of classic side-scrolling action adventure game for DOS, made by Century Interactive and published by BMG in 1995. PSP port is based on a cross-platform game engine recreation by Gregory Montoir.
You’re a pilot of a B-17 bomber in 2nd World War. After you’re shot down by German fighters, you crash land through some sort of time hole in a strange world, where both dinosaurs and humans live. The first thing you have to do is save a princess; she’s your companion throughout the game.
The game itself is a mixture of jump and run and adventure; on most screens you have to think and watch first before you do anything.
