1. can move around
2. can chat
3. (if possible) can perform some action like jump, run etc.
It just to be in isometric pixel art (i can make the graphic for the 'game', just need a programmer)
So...can anyone help me to make it? I can help you to make graphic things, so can you help me to program it?
Thanks and hope to get reply

PS : Additional question, will the 'game' lag if there are many people (again, its in 2D isometric pixel art, not 3D). I hope it will like the FPS game (not using too much server resource, yet not lagging like 'hell')
