I've come up with another way to screw with players.

Originally, I envisioned the buttons being a fixed color. But what if the buttons were just part of the lights the same way the original Simon game was? The difference would be that the buttons are all white. They get their color from the LEDs illuminating them.

So a "turn" in the game starts with Simon blinking the lights and making beeps in the color pattern required of the player (of course, with the color positions all randomized). Then when the pattern is done, all 4 buttons light up with one color each, which allows the player to know where to hit.

I think everyone now knows where this is heading.

There's nothing to say that the button colors themselves must remain consistent. Even within a single turn, they could be made to shift around.

If I can pull this off, it's gonna be a cast iron bitch to play.
