Recently I launched this web based template project that you can use to make your own roguelike game. If you've ever wanted to make your own roguelike game and you know a bit of web development then this is for you.
I'm also recording a series to screencasts which show you how to customise the template to make your own game. It's a walk-through of the whole process, basically a graphical javascript roguelike tutorial which you can follow along with.
Enjoy!
