Night Shift at Block 13

You are the night guard of Block 13 — a crumbling Soviet-era apartment block where something is very wrong. Every night, visitors appear at the window claiming to be residents. Some are telling the truth. Some are shapeshifters wearing stolen faces. One wrong decision — letting the wrong one in, or turning away someone real — ends the night, and the building remembers. Survive all 7 nights. Prove you belong in the block.
