Really enjoyed working through this book, though as an intro to Rust it is probably not for the faint of heart. Other books are better intros. As an intro to ECS, Entity Component Systems, of which most games are made though, I think it was pretty fantastic.

So, 5 out of 5, for ECS. Docking a point, because even though it was fun to use Rust for that, it was a head scratcher at times and I don't believe I am a slouch at coding or how to work stuff out (or times when code was refactored/removed but it was not so clear.).

I also would have liked if it had used one of the main Rust ECS systems, Amethyst or Bevy, rather than bracket-lib as now I feel I have to learn their quirks before I can just roll my sleeves up and dive in.

That said... Really liked it though. Author did a very good job and I normally hate most coding books. Recommended.

(also, would love to see the exact same sort of book written for Go Lang and Ebiten as I am still trying to figure out which would be best for my project(s).).
