4D FIT: Tesseract Puzzle

4D FIT is a neon arcade puzzle about a dimension you can't normally touch.

A shape floats in front of you — a simple 2D polygon, a 3D solid, or a full 4D tesseract — and a wall slides toward you with a hole cut in the exact silhouette of that shape at one specific angle. Rotate the object with the on-screen pads until its shadow lines up with the hole, then slip through for the point. Get it dead-center for a bonus. Miss, and the run is over.

The twist is the fourth dimension. Once tesseracts enter the mix, you're not just spinning a shape in 3D space — you're rotating it through a dimension you can't see directly, watching its nested-cube projection turn inside-out as you search for the fit. Color cues split "normal" rotation from the through-the-4th-dimension moves, so the feel builds intuitively, no math required.

• Fast, one-more-run arcade loop — rounds last seconds, not minutes
