The Utsuro Hotel

You woke up in the stairwell. You don’t remember checking in.

The Utsuro Hotel is a retro first-person horror roguelite where the building decides where you go. You wake in a stairwell with twelve doors and one goal: reach the roof. No door tells you which floor it opens onto, and you only find out once you’re standing in it and the lock has turned behind you. Find that floor’s key to get back to the stairwell, or gamble on the elevator, which is faster, breaks down every time, and doesn’t let you choose where it stops.

The floors hold still: generated fresh each run, then fixed for the whole of it, so everything you learn is worth something. Where the long hallway bends. Which floor buries its key at the dead end. Which door someone is waiting behind. Then you die, the hotel rebuilds itself, and none of it is true anymore.
