This is a stealth exploration game, not a step-limited grid puzzle like Thirteen Step Escape or a shooting-focused survivor like Inferno Soul Walker - pick whichever matches the kind of tension you want.
A fullscreen launcher button sits on the page for a bigger, distraction-free view, and mouse-look works with the pointer locked inside the frame instead of dragging the cursor off the edge - the whole game loads as a compact single-file bundle of about 17 KB behind the Play button.
Adapted from js13kGames/13th-floor (MIT). Single-file WebGL bundle, zero CDN after load.
There is no save file and no account - progress is not kept between visits, so every Play starts back at the first key with a fresh run of the floor.
