# Harvest Hollow
A cozy 3D co-op farming game for two, played in the browser: plant and harvest crops, raise animals, craft, and grow a valley together in real time.
## Description
Two players share one farm in real time from any browser on PC, tablet or phone. The valley spans 40 levels with 25 crops, 16 tree types and 12 animal species, plus 18 workshops with 136 recipes. Progression comes from Mabel's order board, 64 quests, 68 ribbons, 12 collection albums, a seasonal ribbon track, a weekly County Fair, the River Barge, 24 Town Projects and six restoration projects. A hot-air balloon drops loot crates that occasionally contain farm-wide power-ups. No account is needed to start a farm and invite a partner by link; the game is also free to self-host with Node and Three.js. Playable in English and Bulgarian.

A cozy 3D farming game for two, in the browser. Plant, harvest, raise animals, craft and grow a whole valley together, on one shared farm, in real time.
Harness Hollow is a co-op farming game for two. Play it at **[harvest-hollow.up.railway.app](https://harvest-hollow.up.railway.app)** (no account; start a farm in one tap and invite your partner with a link; farms nobody visits for 7 days are deleted there), or host your own. One small Node server runs the farm 24/7, and everyone plays in a browser — on a PC, a laptop, a tablet or a phone. Two people share **one** farm: one plants, the other harvests; one runs the bakery while the other feeds the cows; you both see everything the moment it happens.
## Features - **A whole valley, 40 levels deep** (and Legacy levels after): 25 crops from Wheat to Roses, Coffee Beans and four spices; 16 kinds of trees (fruit, nuts, olives, maple and cocoa, and the Pine for wood) that age a year with every harvest and bear more as they grow old; 12 kinds of animals, from chickens, quail and rabbits to bees, horses, alpacas and bison, with babies, a Nursery and breeding with coat colours, in homes that grow bigger with the flock. - **Craft everything**: 18 workshops and 136 recipes (animal feeds included), queues you drag to reorder and finish item by item, and Compost and Fertilizer for bigger, faster harvests. - **Always a next goal**: Mabel's orders board, illustrated story letters from the townsfolk, 64 quests, 68 ribbons, 12 collection albums, a 30-tier seasonal ribbon track, a weekly County Fair with an NPC league and a horse show, the River Barge, 24 Town Projects that grow a village across the river, six restoration projects ending with Grandma's farmhouse and its room to furnish (40 pieces), fishing and four perk trees. - **Surprises and treasures**: the hot-air balloon drops loot crates on a parachute (coins and XP, sometimes Acorns, Golden Seeds, Fertilizer, an album find or a decor piece). About one crate in twelve also holds a rare power-up for the whole farm: a Rainbow Watering Can, Lucky Ladybugs, a Busy-Bee Swarm, Mabel's Golden Ticket or a Shooting Star. Eight
