It sounds to me that it may have been better to limit performance-critical parts to Rust and write the actual game in something like Lua (embedded in Rust)?

That's the approach I've been taking with a side project game for the very reason alone that the other contributors are not system programmers. I.e. a similar situation as the author had with his brother.

Rust was simply not an option -- or I would be the only one writing code. :]

And yeah, as others mentioned: Fyrox over Bevy if you have few (or one) Rust dev(s). It just seems Fyrox is not on the radar of many Rust people even. Maybe because Bevy just gets a lot more (press) coverage/enthusiasm/has more contributors?
