Thanks, Playtesters!

We've just made the first update to the Moonsigil Atlas playtest. This update adds new map encounters, two new card keywords, and several new cards. The new version also includes bug fixes, balance changes, and quality-of-life improvements.

We'll be aiming to release playtest updates every Friday. The updates will vary in size (some features take more than a week to develop) but at minimum, we'll be getting out quality-of-life improvements and bug fixes every week.

If you want to play the game as soon as possible, we're giving priority access to playtesters who sign up through our Discord server . You can also use Discord to directly submit bug reports, request features, and join discussions about strategy. Otherwise, we'll be rolling out access to Steam sign-ups over time as we improve the game.

Thanks,
Daniel and Jeremy

About the playtest

• This will be an early build of the game, and will not include all of the final characters, cards, and enemies.
• The playtest build will be distributed through Steam Playtest. It will show up in your library like all of your other Steam games, and you can play it whenever you'd like during the duration of the playtest.
• We'll automatically collect some gameplay information, like which cards you buy. This will help us tune the balance and make the game as good as possible for release.
  

Playtest timelines

• We will start with a very small number of playtesters the week of January 27, 2025. Over time, we will include more testers.
• The playtest will receive frequent updates as we add features and fix bugs. Your playtest build will automatically update through Steam.
