A 200-Level Platformer with a Fourth Dimension — Plus the From-Scratch 4D Engine Behind It

HyperDash is a Geometry-Dash-style game in a hand-drawn cartoon look, with one twist nobody else has: the fourth dimension is a gameplay mechanic. Purple portals and dimension orbs swap the world between two layers — a wall that is solid in layer A is thin air in layer B.

It ships together with HyperDimension, the 4D graphics and physics engine written from scratch for the project: tesseracts, exact hyperplane slicing, 4D collisions, a W-axis puzzle mode, and a level editor.
