From the README

A 3D take on Tetris (tetracubes) built with vanilla JavaScript + WebGL2: smooth gravity, collision + locking, row clears, two shading models, and a compact in-page control panel.

Course project (Uni Wien / FCG). The goal was to practice the full graphics stack: matrices/camera, shader pipelines, buffers, and real-time game state.

Note: movement mapping depends on camera mode (orthographic vs perspective) so “W/A/S/D” stays intuitive relative to the view.
