About the Infinity Castle

The Infinity Castle (無限城) is an endless, scroll-driven 3D journey through an impossible Japanese castle, built with three.js and React Three Fiber. You are summoned through a gate in the dark, the floor opens, and you fall into the castle. From there it builds itself around you as you go: corridors of shoji paper and cedar, a tatami room that repeats with small differences, staircases that hang from ceilings, a chamber where gravity turns over, a central abyss of lantern-lit towers, crossroads where every way is open, and false exits that lead only further in.

How to move

• Scroll, swipe, or use W and S (or the up and down arrows) to walk forward and back.
• Left and right choose a way at junctions; Q and E descend or rise where stairs branch.
• Move the mouse to look around. Falls cannot be slowed.

Works on desktop, tablet and phone. Sound is optional. Credits
