-## Lots of TODOs
+## Development
 
-- [ ] AI for NPCs (noob, snowboarder, abominable snowman)

+Useful checks:
+
+```sh
+cargo fmt -- --check
+cargo clippy --all-targets --all-features -- -D warnings
+cargo test
+cargo check --target wasm32-unknown-unknown
+```
+
+Debug hitboxes are available behind a feature flag:
+
+```sh
+cargo run --features debug-hitboxes
+```
