FAQ

Was the October 23 update also version 0.0.4188?
Do not assume that. The October 20 announcement explicitly names 0.0.4188, while the later balance post is identified here by its date. This guide does not assign an unverified build number to it.
Should an early demo screenshot be used for current boss health?
No. The later balance post says health and damage were adjusted in the second half of the Outskirts, including bosses. A screenshot records the displayed build, not a universal current statistic.

This timeline focuses on changes that affect a player’s decisions. It is not a copy of every patch note and does not assign version numbers that the developer did not publish in the cited announcement.

Which October dates matter when reading a guide?

Distinguish the named October 20 patch from the dated October 23 balance pass and the October 27 closure announcement. They answer different questions: whether a behavior was a fixed bug, whether difficulty or costs changed, and whether the demo remained available. A guide should identify which state it describes.

Date Official announcement Practical consequence
October 20 Demo Patch Notes: 0.0.4188 Recheck advice based on older save, reroll or interface bugs
October 23 Dev Update: Balance Pass Recheck encounter targets, resource prices and tutorial instructions
October 27 Steam Next Fest is Done The demo was confirmed no longer available

What did patch 0.0.4188 change for a player?

The named patch addressed problems around saving, reroll selection and communicating danger. The developers fixed early-run saves being rejected and changed death-screen quitting to end the run. They also improved the lethal-attack sacrifice reminder. Those corrections matter when an older recording appears to contradict the current documented workflow.

Read saving and rerolls before treating a death-screen exit as a checkpoint. For the survival distinction, use defense and sacrifice rather than assuming a health-cost item also cancels an attack.

What changed in the October 23 balance pass?

The balance pass reduced difficulty in the later Outskirts and lowered several resource costs. Death’s free rerolls increased to three, while the Mystic’s sacrifice-reset price was reduced without a replacement figure in the announcement. Check the current display rather than inventing a new fixed price or boss-health table from that wording.

The post also introduced fixed-face dice and improved sacrifice tutorial highlighting. Distinguish a die’s available faces from its effect type, and an added explanation from a new mechanic. The announcement does not establish that a later release build will preserve every demo number.

How should you use this history at launch?

Use the October notes to understand the demo’s history, then verify the full game’s own build and announcements when it releases. The developers adjusted the trial while collecting feedback, so a final demo behavior is not a promise that every number remains unchanged in the planned November release.

When reporting a conflict, include the guide date, game version and exact item or encounter involved. That separates a genuine contradiction from an older source that was correct for its time. The demo versus full-game comparison identifies which content belongs to the trial and which is only announced for launch.

Which sources support this history?

The dates and changes come from official Steam announcements checked on November 4. Only the October 20 post is assigned the explicit 0.0.4188 version here; consult the full feed for details omitted from this player-focused timeline.
