Needle in the Hay: Harvest is an interactive farm economy game for TikTok Live. The streamer runs the farm while viewers hire workers and invest money: likes and gifts add hay, and configurable gift rules turn specific gifts into hiring a worker, firing, adding or removing hay, and a bomb. The game features a streamer shop, worker teams, a dog assistant, bombs and round modes. All economy parameters and gift rules (up to 20 commands) are configurable in the game console, with a demo mode and event testing without a TikTok connection.
