Score: 6.5/10 (Innovation: 8, Technical: 8, Documentation: 6, Utility: 4)

Sfera is a sliding puzzle game set in non-Euclidean curved space, using elliptic geometry and a custom 4D Catmull-Clark subdivision algorithm for tile rendering. It uniquely maps puzzle states to harmonic tension in Just Intonation, allowing potential solving by ear, making it a creative blend of math, graphics, and game design.

Target audience: game developers, graphics programmers, math enthusiasts
