Nope, not related to that one at all, but it looks like it was written in the same programming language. A bunch of us were all writing GW-type games about the same time on that forum. Actually, that's the reason I stopped writing my own version (too many similar games)
Anyways, I've been considering polishing it up again and putting it out there for all to see. Give me this week to modify a few things and change the configuration a bit so it works more like an arcade game. I will leave in the analog controls, but will re-configure the keys to work better with sticks. Is there anything standard (keys) that people use for the second stick?
If I don't post anything about it in the next week, send me a PM to bug me about it.
I should also add that I have not tested it on a lower-end machine, but I would guess it may struggle on machines less than 2 Ghz. (My slowest machine is a 2 Ghz And I get mostly 60 fps, with a few slowdowns)
