Dragon's Fury

Imagine an adventure game in the format of pinball, and you get Dragon's Fury. Your hero is a small silver ball, and your battlefield is a three-tiered pinball machine. Using your ball, you can defeat monsters, rack up points, and enter bonus stages. If you play with enough skill, you can trigger all sorts of point-accumulating bonuses. If you get one billion points, you get to fight the final boss and view the ending to the game.
