The paperback is available too!
I haven't had a chance to look it over yet. Such quality assurances will be available in early August for Branching Chaos.

The cover looks kind of like this*:
*IRL, it will have the ISBN + Barcode printed on the white box. It was also brought to my attention to have more of a call to action, so the description now ends with a "!" instead of a "." Oh, and the placement of some other elements may vary slightly.
