The official 1.0.1 changelog is dated October 18 in UTC. Community pages can display a different calendar date because of timezone settings. This article covers that specific note rather than promising a continuously updated patch feed.
| Area | Documented change |
|---|---|
| Achievements | Unlock attempts retry when two achievements happen together |
| Finale hazards | Bloody slimes take longer to spawn and move |
| Certain boss fights | Resource drops respond to player health/inventory |
| Bottle-liquid puzzle | The Hourglass can no longer be moved incorrectly |
| Poster puzzle | Infinite cardboard-piece collection is fixed |
| Finale inventory | A bug associated with dying in phase two is fixed |
Reproduce carefully after updating
Our suggested bug report includes the installed version, the last normal action, what you expected, what actually happened and whether reloading changes it. Use the same starting state for a second attempt. That is more informative than combining an update, new input profile and new save in one test.
These notes do not publish exact boss drop quantities or promise repair of every save created before the patch. A matching description means an issue was addressed in that build; it does not prove that a superficially similar symptom has the same cause. Keep a backup before any manual save intervention, and use the game's official support channels for a reproducible remaining issue.
