- 45% of players who start reach the ending.
- The biggest drop-off is between “A Story of Nobody” (Clear Act 0) and “The Wizard of Oz” (Clear Act 1): from 100% to 82% of starters.
- Only 61% of owners have even the first achievement — the rest barely played.
When it gets good
Share of positive reviews by how many hours the reviewer had played when writing the review.
before it gets good opening up fully opened up
Based on all 572 Steam reviews in every language. Median playtime in a sample of 298 reviews: 13.2h for positive, 10.9h for negative. Almost every game is rated lower in the first 2–3 hours: that window includes refunds and quick first impressions. What matters is how deep the dip is and how fast the game recovers.
Where players quit
Share of players who started the game and reached each story milestone. 100% is the most common achievement (61.3% of owners), so people who bought the game and never launched it don't count.
