Patch notes
These are paraphrases of the Steam news posts, newest first. The wording is mine. The dates and the claims are theirs. I skipped marketing lines that do not change a system.

After launch
- 4 Nov 2026, Experience Optimizations and Bug Fixes. Adds a one-click star-up for characters. The post invites bug reports to the Discord. Further bullet text past the star-up line was not needed to confirm the feature exists.
- 3 Nov 2026, thank-you update. The studio says 15,000 copies sold in the first 24 hours. Ultimate volume was lowered. That sales line is the studio's own count.
