Agreed with most of the comments, played a few rounds and at first thought it was too easy and then got overwhelmed. I played this on linux and did run into a crash too and saw your comment asking what it was so I played a couple more times to see if I could reproduce it
thread 'main' panicked at /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bevy_hierarchy-0.12.1/src/hierarchy.rs:50:35:
Entity 271v4 does not exist
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Encountered a panic when applying buffers for system `recycler::trash::handle_trash_collision`!
Encountered a panic in system `bevy_app::main_schedule::Main::run_main`!
Looks like a timing edge case where an entity no longer exists but it's used in a query or something?
