Curiously, it appears there is. Roughly 18 years after the game originally came out, someone has discovered a trick. It summarize, Bright Man is programmed to use his Flash Stopper at specific points in his health. These are points you're bound to hit using Rain Flush against him, because they're multiples of four. But circumventing these point spots, you can defeat Bright Man without worrying about a single flash.
The above video goes to greater lengths to explain and demonstrate the trick. All in all it's pretty interesting.
So now, so many years later, we learn Top Spin doesn't suck and Bright Man's flash stopping mayhem can be foiled. What's next?
