Stef Passigatti of Switzerland created this game back in 1999, but I just stumbled upon it recently. He also has a few other games on his .kleentec website that you might like to check out. This well-crafted Flash game is a simple shmup that is fast and furious, as well as addictive. He's done a nice job with implementing power-ups, bonus multipliers, smooth animation particle effects, and a high score list, too. So, if you like shmups, you're gonna love SpaceFighta.
