veganpower.grn.dk is Vegan Power, a catch-the-fruit arcade game with a rule you understand in one second: eat fruit, not friends. Fruit falls and you catch it. A chicken, a cow or a penguin falls and you dodge it — each one you hit costs one of your seven hearts. It began in 2020 as a small Flutter and Flame game for Android, released on Google Play that December. In 2026 it was taken apart and rebuilt: it now opens in any browser with no install and no account, keeps a global high-score table on its own small API, and carries a multiplayer beta where two to four players share one arena and shove each other off the fruit.
fantasy.grn.dk is コトバモン KotobaMon — a 3D monster-catching game that runs in an ordinary browser tab, where every monster is a Japanese word. ヒバナ hibana is a spark, コダマ kodama is a tree spirit, and catching one is how the word gets learned. It has a procedurally generated island with five biomes, twelve species, turn-based battles with a type chart, and full Japanese voice-over subtitled in Japanese, romaji and English at the same time. There is no download, no account, no build step and no backend: the whole game is 2,821 lines of vanilla JavaScript plus a vendored copy of Three.js, served as static files.
A look at fantasy.grn.dk, a browser-based 3D game that teaches Japanese with no build step, procedural art and self-hosted AI voice, and what its constraints show about shipping interactive products fast and cheap.
