CELESTAY Craft&Slowlife is a PC (Steam) slow-life game with idle elements from BUBBLE GUM, a Tokyo studio formed by two developers who went independent. The studio announced on September 18 that the game will release on October 8, which falls on October 9 in Japan due to time differences. Japanese display and subtitles are planned, and a demo is available.

The game is set in a world sunk 150 years ago. Players fish in that submerged world while extending a house into the sky. Materials come from clicking driftwood and from fishing, either idle for a set time or manual through a minigame. A partner expands the building automatically, and a merchant who arrives by boat trades fish for materials and items.

Coverage after the announcement describes a full playthrough: Terukazu Yoshida cleared the game in three days with two nights of idling in between. The game calls itself idle, but manual fishing is far more efficient than waiting, so the progression loop leans on the player clicking rather than idling. The story about the sunk world sits behind that fishing loop.

CELESTAY Turns Fishing Into a Tower That Climbs Past the Clouds

Terukazu Yoshida played CELESTAY, a PC idle building game from BUBBLE GUM, and cleared it in three days with two nights of idling in between. Materials come from clicking driftwood and from fishing, either idle for a set time or manual through a minigame.
