That's an excellent article - it's great when people share not only their victories, but mistakes, and what they learned from them.

That said regarding both rapid gameplay mechanic iteration and modding - would that not generally be solved via a scripting language on top of the core engine? Or is Rust + Bevy not supposed to be engine-level development, and actually supposed to solve the gameplay development use-case too? This is very much not my area of expertise, I'm just genuinely curious.
