A first-person math shooter where reloading your weapon requires solving arithmetic problems under fire.
Solve fast. Kill faster.
DOOMATH is a DOOM-inspired arena FPS built in C with raylib (https://www.raylib.com/). You fight waves of enemies across four themed levels (Lab, Sewer, Fortress, and the Final Depths), each with unique textures and a boss encounter. The twist: every time you reload, the game throws a math problem at you - addition, subtraction, multiplication, or division - and you can't fire again until you solve it correctly.
Five weapons, increasing difficulty, particle explosions, floating damage numbers, and a ticking clock. Miss the math and you're dead.
Level 1: The Math Lab. Addition problems gate your reloads. The dino-blob enemies seem harmless. They are not.
Level 2 boss fight. Solve subtraction problems while a horde closes in and the boss eats your health bar.
