I love Rust and wanted to use it for gamedev but I just had to admit to myself that it wasn't a good fit. Rust is a very good choice for user space systems level programming (ie. compilers, proxies, databases etc.). For gamedev, all of the explicitness that Rust requires around ownership/borrowing and types tends to just get in the way and not provide a lot of value. Games should be built to be fast, but the programmer should be able to focus almost completely on game logic rather than low-level details.
Bevy solves the ownership/borrowing issues entirely with its ECS design though.
I had two groups students (complete Rust beginners) ship a basic FPS and Tower Defense as learning project using Bevy and their feedback was that they didn't fight the language at all.
The problem that remains is that as soon a you go from a toy game to an actual one, you'd realize that Bevy still has tons of work to do before it can be considered productive.
