Back Room Survival Guide

You are welcomed from the front room to the back room, where there are countless levels. Level 0 "Front Hall", the linear space is severely distorted, and you may travel in a straight line but return to the starting point. … Level 6 "Lights out", the eternal suffocating darkness makes you feel the whisper in your ears. … Level 73 "red soil", the physical density is about 3.3 Square meters each, and the dark red moon also grins. … Level "Fun", the partygoer asks you to join the party. If you refuse, he will give you an irresistible reason and let you become one of his party. … All of the above are Levels that have already been explored, and there are countless Levels that have not been explored or survived. Good luck if you find yourself there.
