Evaluation
The developer announced on November 22, 2022 that planetarian ~the reverie of a little planet~ would be removed from Steam on December 1, 2022, citing it as "the first VisualArts/Key game on Steam" and thanking players for their support. The game is confirmed delisted — it currently has no purchase options available on the store, consistent with that announcement. This is a completed visual novel (a "Kinetic Novel" with no branching paths) that was originally released in Japan in 2004, with the Steam version launching September 12, 2014 as a localization of the 2010 Memorial Edition. The game received minor post-launch updates including achievement support in August 2015, but no further content expansions were ever planned or delivered. The delisting appears to be a licensing or rights matter rather than a studio closure, as the developer and publisher continued releasing other titles afterward.

About this game
Why don't you come to the planetarium?
The beautiful twinkling of eternity that will never fade, no matter what.
All the stars in the sky are waiting for you.
In time for the 10th anniversary since its original release in Japan, planetarian is an engaging and emotional visual novel from legendary game studio, Key. A sub-brand of VisualArt's, Key are also famed for creating Kanon, AIR, CLANNAD, Little Busters!, Rewrite, and Angel Beats!
Please do not divide Heaven in two...
It is thirty years after the failure of the Space Colonization Program.
Humanity is nearly extinct. A perpetual and deadly Rain falls on the Earth.
Men known as "Junkers" plunder goods and artifacts from the ruins of civilization.
One such Junker sneaks alone into the most dangerous of all ruins -- a "Sarcophagus City".
In the center of this dead city, he discovers a pre-War planetarium.
And as he enters he is greeted by Hoshino Yumemi, a companion robot.
Without a single shred of doubt, she assumes he is the first customer she's had in 30 years.
She attempts to show him the stars at once, but the planetarium projector is broken.
Unable to make heads or tails of her conversation, he ends up agreeing to try and repair the projector ...
For the first time, this heartwarming and memorable title is available on Steam!
It is fully voiced in Japanese, and can be experienced with both English and Japanese text.
