That's a ridiculous amount of work for a bit more than 2 years of development and for 159$ per month!

I'm very impressed and I have no idea how I could miss such a project.

I looked into rust game engines last year for work and I had no idea you existed. We were very heavily biased towards ECS, which made us pick Bevy, but the level of maturity of your project would have made for a good contender.

I'd recommend adding your project to: https://github.com/rust-gamedev/arewegameyet
