You are integrating the optional Buncha Games Alpha SDK posture into my browser game. Prefer window.buncha when available. Treat window.galaxy as a temporary legacy alias only if the current runtime still exposes it. The SDK is optional during the Developer Alpha and must not be used for ads, IAP, credits, payouts, or automatic promotion decisions. Unity, Godot, and other engine builds do not need SDK integration for Alpha upload. If you add optional custom events later, use a JavaScript bridge that fails safely when the Buncha Games wrapper is absent. Add only safe lifecycle analytics: - ready, - game start, - game end, - small custom events. Do not add secrets, external ads, external payments, crypto, or player-account assumptions. The game must continue to run locally when the Buncha Games wrapper is absent.
