The distribution of revenue will be handled through itch.io's automatic revshare system, with each featured developer receiving 15% of the profits, while fordizzy takes a 15% share for its game plus the leftover 10% for marketing, time, and personal greed. The rights and IP to your game remain completely yours.
While new features cannot be added after the anthology goes on sale, you can push bug fixes indefinitely. There will also be a buffer window between the jam's end and the anthology's launch for developers to polish their submissions however they choose, and once fully released, you are completely free to build sequels, reuse your characters, or expand your submission into a standalone project down the line.
