My small hobby toy project, written in Rust language with Bevy's ECS and OpenGL (gl-rs and glutin).
country-slice directorycargo run --release, this will build and run the app
Hi,
After install Rust on macosx and compile the repo appear this error.
Any idea about this error? I'm new to Rust.

It's really minor, since you just expect glslvalidator to be present. But maybe the error message could be improved, or the whole thing just skipping validation if it's not found.
Also, you should be able to do it at build time instead of run time.
Hi, just to say congratulation.
I just see "Tiny Glade" on Stream and the gameplay trailer video, and it reminds me of a game demo written in rust which I have played a few month(maybe years?) ago. But I can't recall the name of the original demo(sorry for forgeting to star this repo :-P).
So I start to search the information about the developers of the game, and finally find this repo out.
I'm so happy that this demo grows into a real game. And I'm looking forward to playing the game sooner!
