📋 About This Mod

A Happy World A Happy World is a psychological and analog horror–themed Minecraft mod designed to slowly distort the feeling of safety inside your world. At first, everything seems normal. But as time passes, strange events begin to occur, entities behave unnaturally, and the environment itself feels aware of your presence. ## Multiplayer Illusion Some events may imitate real multiplayer behavior, including system messages normally only seen on servers. These are intentional mechanics created by the mod and do not involve other players connecting to your world. ## Interface Anomalies Certain interface elements and controls may behave unexpectedly as part of the experience. These effects are intentional and temporary, and do not affect your game or system outside the world. This mod focuses on atmosphere, tension, and unpredictability, rather than traditional jump scares. Mysterious signs may appear inside houses, unfamiliar entities can watch you from a distance, and certain moments in the world feel intentionally wrong. These events are triggered naturally through gameplay and time spent in the world. A Happy World is meant to be experienced alone, with sound enabled, and without knowing exactly what will happen next. It does not guide you, explain itself, or warn you clearly. The world simply changes — and it expects you to notice. Nothing here is broken. Nothing here is safe. WARNING!!! ## ⚠ Sensitive Feature Disclosure This mod intentionally performs system-level effects for horror immersion. The mod may: - Create a harmless .txt file on the user's Desktop as part of a scripted event - Briefly access the user's webcam to display a visual effect inside the game Important: - The file contains only fictional text related to the mod - No personal files are read or modified - The webcam is not recorded or stored - No data is collected or transmitted - The mod does not connect to external servers All actions are local and exist only for the horror experience. **MOST IMPORTANT PART!!!** It creates harmless EICAR (antivirus test) files on the user's desktop, opens the command prompt, presses the F11 and F5 keys, generates numerous .txt and .bat files, and exerts psychological pressure on you to kill yourself. Contains elements related to epilepsy and loud noises. By playing the mod, you assume full responsibility =)
