I've found tons of nice spirites by googling and started to make Javascript RPG which would be quite simple at start. Now I have finished making a simple and working world for the game with blocks, people, doors and so on. I would appreciate help with designing gameworld and designing and coding the battle system and other stuff which I haven't done yet. If you're interested and know some CSS, (X)HTML and Javascript or have other skills that could be useful please let me know.

I think that's really cool. But why stop there? If you know javascript, you can go to dxStudio.com and get a great free version of the gaming engine to build interactive games outside of just RPG's... complete with graphics and such.

They have great wiki style tutorials and step by steps to get that rolling.

However, I'd be more than happy to help you if you wanted, with whatever I can.
