Combos in a fighting game

[Brisingre]

This is, in my opinion, a very nice way to visualize combos. It is also, hopefully, written easily enough for someone without much experience to understand.

I'd rather use a string instead of actives for a combo system.
Like:
* Upon pressing W
> Set String to String + "w"
etc..

* Right$(String,3) = "qwe"
> Set String to ""
> Do Action

And optionally you can make a timeout that resets the string after a certain time has passed without key presses.
