Greens

Greens is a top-down farming RPG that fits in about 100 KB and starts the moment the page loads. No download, no account, and no external art or audio: every sprite is drawn in code and every sound is synthesized in the browser.

Its one real trick is breeding. Take two seeds to the breeding bench and the offspring inherit a blend of five genes — color, yield, growth speed, value, and hardiness — with a chance of mutation throwing something you didn't plan for. The traits are visible: a strain's genes shift the plant's actual color on screen. Stabilize a Gilded, Ironleaf, or Verdant line you like and it serializes to a short seed code you can paste to a friend.

Around the breeding sits a full farm. 39 crops across four seasons, a day/night cycle and weather, a mine with combat and ore, fishing, cooking, eight villagers to befriend, and a main quest to restore the lost Ancient Green. Six skills level as you play, three save slots, autosave when you sleep.
