About the game
Compile & Defend is a tower defense game where towers aren't aimed by clicking — instead, you program the logic they run on every tick, using Python, JavaScript, C++, C#, Rust, Zig, or Lua. Conditional statements like if let you prioritize incoming threats, for loops help clear out swarms, and your code routes air, armored, and camouflaged units to the tower best suited to handle them. Success comes down to writing smarter logic rather than simply placing more towers. The game is being developed and published by Codx.io, planned for 2026.
