Client is managed with bun. Get bun if you don't have it.
Then, bun install in packages/client.
Client (packages/client) is vite + SWC + ts + rxjs + phaser + react. Run with bun dev. Don't forget to add a .env with appropriate env variables.
Backend and local client (packages/phantom-client, packages/server, packages/worker) are rust (rocket). Install dependencies, build, and run with sh start.sh from packages. Test with sh test.sh. Sometimes stuff is really finnicky so you might have to try a couple of times.
