npm run init -- --name "My Game" --engine godot --mode prototype --non-interactive --competitor "Mini Metro" --engine-version "4.4.1"
npm run templates -- list
npm run validate -- --project projects/my-game

After build/link/install, the package bin is available:

npm exec open-gamestudio -- --help
npm exec open-gamestudio -- templates show gdd
