I've been interested in checking out Handmade Hero, but haven't yet found the time to start looking at it. One thing I would like to know though is what game they're actually making. Now that it's been going on for some time, is there a video somewhere of what kind of game is being made?
You might want to check his YouTubee stream[0]. He's currently finishing the lighting engine; if you browse through his latest video, you will occasionally see how the scene looks like.
