I learned a lot about Rust by making games with Bevy and writing down everything I learned: https://taintedcoders.com/

The smaller the game the more likely you are to finish. I usually started with making the movement fun and then developed some game like concepts around it.

I also highly recommend starting by making simulations instead of games as when you're alone they are still a blast to see come alive. Building boids is a fantastic exercise I do in any new engine.
