You can still pre-order the NoGood Book if you want to help make the slipcase stretch-goal a reality.
The Collectors Edition includes collectibles such as an art print & sticker pack, and a slipcase if we reach the stretch-goal. These will not be available ever again when the pre-orders end.
If you don't need extra goodies, there's also a book-only option.
