I've been working hard this month on a new template project to help you make your own roguelike game. It's called Roguelike Browser Boilerplate and it includes basically everything you need to get your browser based roguelike game started. The annoying stuff like title screens, menus, touch input, sound effects, mobile device testing, dependencies, and tileset graphics integration are all taken care of, all you gotta do is turn up with your ideas and start coding.
I'm just putting the finishing touches on this and I'm gonna release it at the end of the week.
Ok, back to coding! \o/
