Small games for the hour after midnight.

Four people and a cat in an old rice shop by the Kamo River. Our next game, Kuu's Night Post, comes out in spring 2027.

Stage 01The new game

Kuu's Night Post

A cozy delivery game about the letters nobody answered.

Trailer 01 · in-engine
00:00 / 01:12

Every night at two, the valley's last post office opens for one courier. Kuu has until first light to deliver forty letters to people who stopped writing back years ago.

There's no map and no quest log. You learn the valley by its lights: which windows stay lit, which shortcut floods when it rains, which dog follows you to the bridge. Deliver a letter and, some nights, a reply is waiting at the counter the next evening.

"We wanted a game you can play at 2 a.m. without waking anybody up. Including yourself."

Kaede Tachibana, director

Stage 02How it plays

Five rules for a gentle night.

Rule 01 / 05Kuu learns the valley

  1. 01

    Forty letters, no map.

    The valley has no map screen. You learn it the way a real courier does: the bakery that lights its ovens at four, the lane that floods, the house with the blue noren. By night ten you'll stop getting lost. By night twenty you'll have favorite shortcuts.

  2. 02

    Every letter can be answered.

    Forty people, one hundred and twelve replies, and a few that never come. Read them at the post office counter, write back in your own words, and watch the valley change as people start talking again.

  3. 03

    One night is forty minutes.

    Each night runs from two in the morning to first light. Miss a delivery and it waits until tomorrow. Nothing is lost; the bag just gets a little heavier, and Kuu walks a little slower.

  4. 04

    Nobody fights. Nothing fails.

    No combat, no game over, no timer you can lose to. The hardest thing in the valley is a shiba named Bun who insists on walking you to every door, and a cat who sleeps on the parcels.

  5. 05

    Four channels of music.

    Rin wrote 23 tracks using only four sound channels: two square waves, one triangle, one noise. It plays quietly on purpose. The soundtrack comes free with the game, and on cassette for the stubborn.

Stage 03The back catalog

Four cartridges, one shelf.

Every game we've made, from a nine-week game jam to the one that took four years. All on Steam, and DRM-free on our own little store.

Six frames and a heavy bag: how Kuu learned to walk

Preview speed

Kuu walks in six frames at ten frames a second, on a 16 by 24 pixel grid with eight colors. Our first version had eight frames and looked like ice skating. Cutting two frames made the steps feel deliberate.

The trick is the bag. It lands one frame after the feet, so the whole body reads as carrying something heavy. Try the onion skin: you can see the bag lag behind the bob.
