Players create a hero, pick a difficulty, and work through a sequence of gyms — Arithmetic, Multiplication, Fractions, Algebra, Geometry, and beyond — each built around one subtopic and gated by character level. Every gym ends in a timed boss duel; some have a mid-gym checkpoint fight too. Correct answers earn XP and cash; misses cost HP. Running out of HP doesn't erase progress — it either fully heals you for free (if you could have afforded it anyway) or knocks you down a level or two and moves on. The Clinic lets you pay ahead of time to avoid that risk entirely.
A math RPG: subjects are gyms, bosses test skills, wrong answers cost HP.
