Looks like very nice work, I look forward to playing with it!
Being really nitpicky here (but I'm guessing that's what you're after): I'd consider scaling down the 3200x1800 1.6meg header image you have in your readme. I think the widest a readme image will scale to is 830px (894 - 32px padding), so you could scale it down to a quarter of the current size without losing anything visually. The slow load is the kinda thing that might put some of your target audience off.
