Love what you're doing here! A friend of mine have been working on a Pong clone in order to learn Rust and plan on documenting our experience. In particular, what are the valuable aspects or takeaways from these kinds of post-mortems? The reason I ask is as a result of using Pong as an example to learn Rust better, I'm finding a ton of language specific material I could document as opposed to game mechanics. Trying to find the right balance of material.
