Greenfoot, one of our development environment, has a new feature. And it is one of my favourite features so far: You can export your finished Greenfoot scenarios as a stand-alone application or, in fact, straight to a web page.
But now, what’s new is this: put your game straight onto the web. Have a look – it works!
So now: invent your game, program it, and export it to a web page. Then, all you need is a server to stick it on, and your grandma will be playing your game in no time.
