All is number; within numbers lie games, within games lies the Way. In Numeralea you face the Entropy — a chaos of numbers closing in. Roll your dice, choose a set that sums to the target, and dissolve it before it reaches you. Land prime numbers, perfect squares, Fibonacci runs, Pythagorean triples, perfect numbers and more — fifteen mathematical relations in all — to unleash powerful resonances. A roguelike where every run is a new equation. Build your dice and modifiers, and travel with legendary mathematicians — Plato, Ramanujan, Euclid, Pythagoras, Lagrange, Goldbach, Fermat — each with a unique power. Choose your Calculus stone, push from Basic to Advanced, brave self‑set Challenge mutators, or descend the endless ∞. Drawn in the style of a da Vinci codex: sepia ink on parchment, astrolabe geometry, and adaptive music.
