What is Instant Anastasia?

The sleeping crew’s nightmares consume a spaceship in this first-person horror roguelite. You explore procedurally generated areas, gather supplies, and rescue survivors, dividing limited resources between combat and repairs. Environmental disturbances and a detection device help you locate threats; entering the nightmare makes enemies visible, but losing all your sanity means game over.

For you if...

+you enjoy slow, cautious exploration and deciding when to retreat

Not for you if...

−you prefer straightforward action without managing survival needs
