Tesseract

Tesseract is a sci-fi physics puzzler where an astronaut is swallowed by a black hole and wakes up on the surface of a tesseract — a four-dimensional hypercube floating in the void.

What makes Tesseract unique is its gravity system: every face of the cube is walkable. Step off one edge and the world rotates beneath you, pulling you onto the next surface seamlessly. The entire cube is your playground.

Spread across the six faces are four types of physics puzzles — socket puzzles where you carry objects across gravity-shifting surfaces, trigger plates that require weight and timing, star puzzles that trace ancient constellation patterns, and moving platforms that speed up as you get closer to solving them.

At the heart of the cube sits the Gateway face, home to four dimensional doors. Each one leads somewhere completely different:

• Mirror Dimension — physics and logic run in reverse
• 2D Realm — you're flattened into a silhouette, navigating by shadow
• 5th Dimension — space folds over itself in layered loops
• White Room — total white void, navigated by sound alone

Throughout the journey, ARIA — an AI built into the astronaut's spacesuit — narrates the story, reacts to what you do, and offers hints when you're stuck. She gives the game its emotional core.

Built with Unity and C#, Tesseract is a competition entry under the Physics Puzzler theme — a game where every mechanic, from carrying an orb across a rotating face to listening for platform edges in a white void, is grounded entirely in physics.
