📐 One detail I forgot to mention in my previous post.
The name Tetragon comes from the Greek word tetragonon, meaning quadrilateral or four-sided shape.
That's one of the reasons I chose Mr. Square as the app's mascot. A square is one of the most recognizable geometric shapes, making it a natural fit for a math-focused app. The name and the character both come from the same world of geometry, helping create a consistent identity for Tetragon.

Name, shape, mascot — all from the same concept. That's proper brand thinking 👏 Mr. Square celebrating a 10-in-a-row streak is such a satisfying detail 😄🔥
