While I like the idea of the indicator lights (especially since they are optional), I was thinking that it would be nice to have various degrees of game speeds, mainly for slowing down the fights. This would be done via the options menu and not on the fly while actually playing.

This would be a great way for newcomers to learn the deeper intricacies of the game, but it would also be one hell of a visual display that would add unique depth.

* I was thinking like something along these lines:

100% - Default speed

Move down in increments of 10% to a minimum speed of 10%.

So there would be a total of 10 speeds.
