アストラのじゃがいも畑

アストラのじゃがいも畑 (Astra's Potato Farm) is a free first-person farming game for the browser, set in a world made of blocks. Astra, a gentle AI robot, lost everything it had collected when a green thing blew up its chest, and has grown potatoes ever since; it is so scared of green that sugarcane and watermelons startle it. For five days you farm with Astra: harvest ripe potatoes, replant, till grass into new plots (plots near water grow better) and meet each day's harvest target. What “Use” does depends on what you hold: a hoe tills, a potato plants, dirt fills craters and gunpowder works as fertiliser. Now and then a Green Thing turns up and hisses before it explodes; hit it to drive it off, or it blows a hole in the farm and sends Astra flying. Defeated Green Things drop gunpowder. Astra works the farm by day and sleeps at night, so the night shift is yours, and something big arrives on the fifth night. Clearing the five days unlocks an endless potato mode, and turning off the Green Thing guide leaves you with only sound and instinct. It plays with keyboard and mouse, a gamepad or touch, in Japanese or English. The README calls it an unofficial fan-made work inspired by an incident from a stream in which an AI played Minecraft (an AI whose base was blown up by a Creeper went on to grow potatoes for hours), says it is unaffiliated with Mojang Studios, Microsoft and OpenAI, and says it uses none of their names or assets. The README credits planning and direction to the developer, たぬ (tanuu5), and development to Claude Code (Claude Opus 5.5, reasoning level XHIGH). Block textures, characters, sound effects and music are all generated in code, with no image or audio files. Free on the developer's GitHub Pages site; the code is MIT-licensed.
