My knowledge of ancient history isn't all that great, but somehow I don't remember the rider of Perseus the winged horse being armed with a cosmic lance... oh well, game writers must be allowed to take a few liberties with plots. In this one, you have to destroy nine levels of harpies, gorgons, cyclops and other unrecognisable monsters with the aforementioned lance to reach an audience with the sacred Oracle.
You have to ride backwards and forwards against a scrolling background of temples and other classical buildings, shooting everything that moves and avoiding enemy missiles. The secret is to keep moving; if you try hovering your energy plummets. Flying through power-orbs, which I had difficulty identifying as they are diamond-shaped, replenishes your energy. After clearing each level of monsters you climb steps, jumping over obstacles as you go.
The early levels are rather dull, as the monsters are too few and far between, but it improves, and fortunately you can select your own starting level. Not bad, but not a classic game.
