I just stumbled across the site while researching HTML5 game topics, and I thought I'd post a project I'm currently working on using canvas. I'm currently developing a dystopian roguelike game called Bad Transaction. It's a single player game with a custom 2D engine, and a custom node server backend. I've been working on it for a little over a year now, and I'm really hoping to have a very, very, early alpha ready at some point this year. Here's the latest development progress video: https://www.youtube.com/watch?v=IY30ohow1lM.
