Then do it. The game is open source, all you need is there :)
Read GPL. As long as you provide the source it's fine, probably. Read it.
Or donate it to a charity or give it back to Simon as a way of saying thank you for TPT.
It has the option of Iframe or unity... how to upload it now? http://www.kongregate.com/games/glenzo/the-powder-toy-from-powdertoy-co-uk/version
I cant do iframe, it only brings up the website. I cant do unity, because powder toy is an exe file, not a swf or Unity3d file. HOW THE HECK AM I SUPPOSED TO DO THIS!
