I took the code from SharpOT: OTBM Reader, XML Reader, OTB Reader.
There is a stackorder bug when loading map (with Lava).
Features:
Load a map and parse it into the game.
Multiple players can login and talk.
You can't move it's bugged and I can't figure out why. (You move, but you can't move again, I had it working once, then It didn't worked anymore...)
