First Principles: A Calculus Platformer

First Principles is a calculus-first learning game: a 2D platformer built on a live graph. Your path follows y = f(x); the derivative shapes where you can stand, where it breaks, and how the level "teaches" each idea. It's math you see and move through, not only read about.

Why play it

Feel the derivative — Platforms and hazards follow the curve and its slope logic so f and f′ stay connected in your head.
