Joe & Mac - Caveman Ninja

A port of an interesting arcade game by Data East about two cave heroes who have to rescue kidnapped ladies. The port is not as intense as the 16-bit versions: the levels are simpler and there are fewer of them, and the rescued ladies don't thank the heroes. If you want to familiarise yourself with the game, you should also check out the SNES and Genesis ports, or the original on arcade machines.
