Yesterday the first EVER online game of Magma Duel took place between me and two others in my Computer Engineering class whilst other work was supposed to be being done. ;)
All in all, it worked pretty nicely. The only bug (big one, however :P) are that players can sometimes die on one client's screen, and then come back to life if they are still alive on another client's game, resulting in an 'undead' stick character beating on everyone, invincible to their attacks. Doh!
Much more work to still be done, it seems.
