わすれもの駅

わすれもの駅 (Wasuremono Station) is a free, quiet 3D exploration game for the browser. Tsukimizaka Station has stood empty for a long time; sunlight falling through a hole in the roof wakes Tomo, the little guide robot of the station's lost-property office, whose job is to find seven lost things left somewhere in the station and get them back to their owners. Picking one up makes its owner's memory appear as a faint afterimage. There is no combat and nothing frightening: you walk and look around a vine-hung concourse, a dark flooded underground passage you light with a lantern, an underground shopping street whose collapsed floor has become a slope, and platforms buried in grass. A notebook lists what you have found and hints at where to go next, a station map shows where you are, progress is saved in the browser, and after the ending you can walk the station again at dusk, when a few new things have appeared. It plays with keyboard and mouse, a gamepad or touch, in Japanese or English. The README credits planning and direction to the developer, たぬ (tanuu5), and development to Claude Code (Claude Opus 5.5, reasoning level MAX). The station, robot, plants, signs, light shafts, music and sound effects are generated in code; the only image files are a calendar, a piece of graffiti and a timetable poster that the developer made with ChatGPT. Free on the developer's GitHub Pages site; the code is MIT-licensed.
