SteamAbout Knock Twice
Someone is knocking. Count carefully.
Garland Court, 1974. The rent on apartment 4B is impossibly cheap, and on your first night the old woman across the hall slides the house rules under your door:
if someone knocks TWICE — only twice — do not answer. do not speak.
they are not asking to come in. they are asking you to come out.
The woman across the hall has been dead for six years.

Four apartments. Four ways to be afraid.
Knock Twice is an anthology of doors. Each unit of the building hands you a different instrument of dread — and then takes the last one away.

The 1-bit limit IS the horror
Two colours. Pure black, pure white. You can never be certain what you saw through the peephole — the aesthetic is the mechanic. No gore. Just silhouette, negative space, and the wrongness of a shape you can't quite resolve.

Sound is the monster
Every sound in the game is synthesised from scratch at runtime — there is not a single audio file in the build. Each visitor has a knock rhythm you learn the way other games teach enemy silhouettes. The mix drops to total silence for two seconds before every double-knock. Play with headphones.

Rules you learn, then rules that lie
The difficulty curve is not stat pressure. It is the steady corruption of what you know. Night one teaches you that three knocks are safe. Later, something knocks three times in the superintendent's voice. Every safe pattern eventually gets counterfeited, and your own knowledge is the resource the game spends.
