I'm working on a specs based rewrite with gfx, rodio, and glutin
Hey @kvark ! Yeah since making that comment I've had some additional thoughts. What I'm considering rewriting Nitro into appears to be pretty much exactly what Amethyst already is, so I'm considering making contributions to that alternatively. I'm kind of adrift on what the best approach here is honestly because I like the API style I have for Nitro on my master currently but from a performance standpoint the Amethyst approach looks vastly superior. I reviewed the pong example for Amethyst and I like the technological merits of it but the code itself looks kind of gnarly. (Maybe it should be more than one file? I'm not sure I haven't experimented with that.) I wonder if perhaps I can improve amethyst with additional tutorials.
I also took a look at the Amethyst progress section and I noticed audio components missing. I'm a contributor to rodio so I have experience with audio APIs. I might take a swing at implementing that if the offer interests you.
