The answer first
There is no official universal completion time in the checked store material. One supplied creator who reviewed the game after 100% reported finishing that completion run in a little under 20 hours. Treat that as one experienced player’s result, not a guaranteed average.
Last updated: August 24, 2026 · Official store pages plus clearly labelled creator observations supplied for this build.
What is verified
- The official game includes optional investigations and exploration that can change playtime.
- One creator reports a sub-20-hour 100% run.
- Difficulty, reading, exploration, and replay goals can change the total.
What needs more evidence
- A universal main-story average is not claimed.
- The creator result is not promoted to an official number.
- Holloway Manor playtime is not combined into a guaranteed total.
What to do next
- Decide whether you will pursue optional investigations.
- Allow extra time for reading clues and resource management.
- Expect a first run to differ from an experienced review run.
- Use the estimate as planning guidance, not a promise.
The available estimate
The completion-review video states that 100% took the creator a little less than 20 hours. Because this is one reviewer with advance access and a specific play style, the number remains a creator observation.
What makes a run longer
Optional investigations, backtracking, clue reading, inventory management, difficulty, deaths, and searching for upgrades can all increase playtime.
What makes a run shorter
Skipping optional content, using known puzzle answers, lowering puzzle difficulty, and replay familiarity can reduce the total.
Use the number responsibly
Plan for variation rather than setting a hard deadline. The strongest use of the available figure is to show that this is not necessarily a sprawling hundred-hour open-world game.
