Cave Harrier (madjackmcmad)
"Fly through dark caves and over scorched rock as you head beneath the surface of a doomed world!
If you've played Space Harrier, you know exactly what you're getting in to. If not, the game is easy enough to pick up: you fly around, shoot the monsters, and dodge the pillars of things that smash into you. There are three stages, the entire game is a short trip around 5 or so minutes." - Author's description
