SMod: Sandbox in Backrooms

About SMod: Sandbox in Backrooms: Mod-Style Backrooms Simulator with Enemies and Quests

SMod: Sandbox in Backrooms is a mod-style game built around the sandbox and the Backrooms. It runs as a real-time simulator where enemies spawn dynamically and levels await completion. The core loop combines spawning monsters through a portal gun, completing quests, and hunting for weapons across the environment.

Several scenes show an uneven dark brown surface set against a black, star-filled background with a visible galaxy cluster. A large, pixelated sphere resembling Earth appears in the center background across multiple views. In one scene, a large green face with wide eyes and a red mouth is visible on the left side of the frame.
