I have had some ideas in the past that play on speed. Perhaps once I've finally got all my JJ2 stuff on this computer, I'll show you all.
In the meantime, though, I think that JJ2 can definitely be very fast, and the 640x480 resolution can make that speed not as unforgiving as in JJ1 was when you went fast(Having said that, JJ1's main campaign is much more fun than JJ2's, in my opinion).
