I've found this to be the most useful tool of the Jam - already used it for two realms! I love how it sets everything up, giving a starting-off point for every feature/Myth. I also like the different generation styles - plenty of scope for whacky or realistic geography.
Mmacphail, the developer, was super responsive with tweaks and fixes. I had an issue with dark-mode readability which was quickly resolved. Thanks again!
