I plan on making a rather simple dungeon crawler here. In this very browser window. I will use advanced css techniques and some javascript. To store progress we will use a cookie. Which can be deleted, but that's life!
Thanks to NeoCities! Neocities offers great free hosting for basic websites. There is no server side php, asp, ruby, etc but for basic html websites its pretty darn neat. And you can't beat the price!
See what I've gotten done on the Game.
