Maybe they just shouldn't make game which gameplay is relevant to your cpu speed?
It's not that Super Crate Box runs faster than it was designed to if you have too good a CPU. It's that some people find the game to be too fast paced for their tastes and have found that it can be slowed down by bogging down their CPU (actually reducing the speed of the game, rather than having it play at the same speed but with fewer frames rendered.)
Personally I like it being intense and speedy. It isn't the type of game that you sit down and play for hours, but it gives me some rapid entertainment.
