Hoshino Shirusu Shinjitu Is Now Free on Steam, With the Story Changing When You Close Your Eyes

Hoshino Shirusu Shinjitu, officially titled 星の記す真実 in Japanese, is now playable for free through Steam. Team Komori previously announced the Japanese Steam launch for October 5, 2026, following the game's earlier release as a free browser title.

Its central idea is unusually simple: the narrator tells the player to close their eyes. Actually following that instruction or continuing to look at the screen can change how the story unfolds, while conversation choices lead toward multiple endings.

PV, Steam, and Hoshino Shirusu Shinjitu Visuals

Closing Your Eyes Becomes Part of the Narrative

At the beginning of the game, the narrator asks the player to close their eyes. Hoshino Shirusu Shinjitu then uses the player's response to that instruction as part of how its story is experienced.

Traditional dialogue choices still matter, but listening without constantly relying on the screen gives its sound-novel format a more unusual role in the storytelling.

A Conversation on a Boat Opens the Past

The protagonist wakes aboard a boat, where a mysterious woman says she will talk about their past and asks them to answer her questions.

Memories and information gradually emerge through that conversation, while the player's answers influence the eventual ending.

The Steam Version Remains Free

Team Komori has not converted the game into a paid release for Steam. The store lists it as Free To Play, with the Play Game option already active.

The Steam version also supports full Japanese audio, while English and other languages are not currently listed as officially supported.

A Short Game With Multiple Endings

The estimated playtime is approximately one hour, but the game includes multiple endings. Its compact length makes replaying different choices and approaches a practical part of the experience.

Team Komori also warns that the story contains emotionally heavy material and recommends playing in a comfortable state and environment.

Why This Matters

1) A physical instruction becomes part of the storytelling

Closing your eyes is not simply a promotional gimmick; it affects how the player receives the narrative.

2) A short sound novel with multiple endings

The roughly one-hour runtime makes it easier to revisit alternative choices.

3) The Steam release remains free

Moving from free-game platforms to Steam has not changed its distribution model.
