Signal Orchard Microgame Kit is an original, brand-free cozy automation prototype centered on a small loop: place relay nodes, connect orchard signals, and keep the harvest route stable. It includes a playable browser demo, an interaction guide, modular prop specifications, UI icon notes, level tuning values, and a fictional sample scene. The demo is dependency-free and useful for evaluating the interaction before adapting it to a preferred engine. The package contains no third-party characters, logos, trade dress, or extracted commercial assets. It is a prototype foundation, not a finished commercial game and not a promise of player retention or revenue. The included license permits use inside one buyer-owned project only. License: one buyer only; non-transferable; no resale, redistribution, sublicensing, marketplace upload, standalone client delivery, or competing derivative product. The source remains owned by the seller.
