Starlit Hearts: Idle Star Collector

A cozy idle dating sim where you fly a little starship between the stars, collect Stardust, and help nine lonely girls remember they once loved you.

Free web demo coming soon, then mobile (iOS and Android) and PC.

✦ The story

They forgot you.
Help them remember.

Every Starlit lives alone on her own little star: an idol on the Music Moon, a bookworm on the Library Planet, a chef in the Kitchen Nebula. Your starship gathers their Stardust, turns it into handmade gifts, and wins back their Affection.

But every Heart Rebirth, they forget you. Rebuild their memories one keepsake at a time, fill their rooms, go on dates, and play their cozy mini-games until every Starlit remembers you for good. 💖

Meet the Starlits

Hana

Hana

the Idol Singer · Music Moon

Thousands of fans, but nobody knows the girl off stage. She is the first to hear you, and one day the one who always remembers.

Shiori

Shiori

the Bookworm · Library Planet

She lives in stories because real people felt too loud. She wants a reader who sits beside her and doesn't need to talk.

Kiko

the Chef · Kitchen Nebula

She still cooks huge meals for a family that moved away. She needs someone who asks for seconds.

Miwa

the Artist · Atelier Star

Her paintings never have people in them. She is waiting for a face worth painting.

Rin

the Pro Gamer · Arcade Comet

A thousand teammates online and no friends. She wants a player two who stays when the match ends.

Mei

the Couch Potato Cutie · Rerun Planet

She stopped going out and told herself she liked it. Staying in is better with someone.

Akane

the Tsundere · Letter Planet

She pushes people away before they can leave. Her planet is full of letters she never sent.

Yoru

the Night Walker · Lantern Star

She can't sleep, and the night is the only quiet time. She wants company for the long way home.

Sora

the Deep Talker · Harbor World

She listens to everyone, and nobody asks how she is. Ask her “how are you, really?” and wait for the answer.
