Joust 1980

Left/Right to run, Space to flap and stay airborne — collide with shadowlords, hunters, and bounders from above to knock them out, or lose one of your 3 lives if they catch you first. A pterodactyl shows up as the score climbs and only goes down if you hit it in the mouth; miss and it costs you a life anyway. Score 20,000 for an extra life.
