4D Golf

4D Golf is exactly what its title suggests — golf played in genuine four-dimensional space rather than 3D space with a clever framing. The fourth spatial dimension is real, hidden objects extend into it, and the puzzles ask you to navigate spaces whose geometry doesn't behave like anything your brain has learned to handle. The game's primary teaching tool is the gameplay itself, gradually building intuition for moving through and around the hidden axis.

Over 120 levels run across seven vibrant themed worlds, each introducing new ways the 4D mechanics interact with course design. Hidden paths exist in directions your 3D camera can't show directly. Moving platforms shift through dimensions. Gravity can be reoriented. Speed boosts launch the ball in directions that look impossible until you learn to read the visualizations.

The visualization options are central to the game's accessibility. Multiple different ways of rendering 4D space help different players find a representation that clicks for them — cross-sections, projections, ana/kata-axis shading. Once you've started to see the fourth dimension, the puzzles open up rapidly; before that moment, they look impossible.

A built-in level editor lets you build your own 4D courses, and a Marble Platforming Mode rewards speedrun play with time-attack races through specific courses. Unlockable accessories reward completion of harder challenges. The game functions equally as a puzzle game, a golf simulator and a math-explainer — somewhere between a recreational toy and a genuine tool for developing geometric intuition you didn't have access to before.
