Compile & Defend
Live player count and Steam charts
A tower defense game where you don't click to shoot — you write code your towers run every tick, in Python, JavaScript, C++, C#, Rust, Zig or Lua. Prioritize threats with if, sweep swarms with for, and route air, armor and camo to the right tower. Better algorithms beat more towers.
