A native and WASM-compatible 2D particle system plugin for bevy
Note: This crate is still under development and its API may change between releases.
The above was captured running a release build of the basic example, cargo run --example basic --release, and ran at 190-200 FPS on a
2019 Intel i9 MacBook Pro, rendering about 10k particles.
