How many achievements does TSUMIMI TIME have?

Sixteen. Nine are ending achievements, four are collection achievements, two are coverage achievements and one is a story milestone for watching the Day 1 stream.

Which achievement is the hardest?

All Survey File Acquired, at 0.4% of players. It is lower than every ending achievement, which tells you that finding every file is harder than reaching any single ending.

Why do the rates change between visits?

Because they are live Steam figures that move as more people play. The page is regenerated from the newest snapshot, and older snapshots stay in the repository so the change is auditable.

Do I need every ending for 100%?

Yes for the All Ending Seen achievement, which sits at 2.2%. The nine ending achievements each unlock individually, so you can collect them across separate saves rather than one perfect run.

Does the demo count toward achievement rates?

No. The demo is a separate AppID and has its own statistics page. Everything on this page refers to the full release only.

All 16 TSUMIMI TIME achievements, rarest last

Steam lists achievements in internal order. We re-sorted the same 16 by global unlock rate so the ladder is visible: the first row is the one almost everybody gets, the last row is the one 0.4% of players have. Rates come from Steam's public API and are stored in this repository.

The shape of the ladder

Nine of the sixteen are ending achievements. Only two rows are above 50%, and both are structural: watching the Day 1 stream, and failing the final deduction. Everything else is a branch you have to aim for — which is why the four rarest rows are all collection achievements rather than endings.

Rates from Steam global achievement stats · 2026-10-24 05:48 UTC

How we got these numbers

Unlock rates come from GetGlobalAchievementPercentagesForApp and names, descriptions and icons from the public Steam community stats page, in both English and Japanese. Every row is refreshed together, so a name and a rate on the same row always come from the same snapshot. We do not average rates across snapshots.

Reading the ladder correctly

A rate is the share of all players who own the achievement, not the share who are trying for it. On a two-day-old release the denominator is still small, so rates drift upward for weeks. Treat a 2.7% row as 'rare right now', not as a permanent difficulty rating.
