Some graphics cards can treat both monitors as just one really long one - in which case it would work fine, you'd just have to make your game span both and position your elements accordingly...
Got it. I'll try it with the SPAN DESKTOPS setup (when I get everything dialed in!) and report back.
may i point out that most people only have 1 monitor per pc. a lot of people won't be able to play this.
I'm making this game for a dedicated arcade cabinet with a half-silvered mirror and specialized controls, etc... It actually makes it easier when I don't have to worry about various resolutions, CPUs, GPUs.
I might try to make a more vanilla version for use on a regular PC (That one'll be single monitor only!)
