Compile & Defend

You don't place towers. You program them. Compile & Defend is a tower defense game with no click-to-shoot. Every tower on the field runs your code, once per tick. Write a smarter script and your defense gets smarter — write a sloppy one and the swarm walks right through. It's the tower defense game for people who'd rather refactor than micromanage. Write it in your language There's no proprietary scripting dialect to learn. You write in a clean subset of a real language you already know — pick from Python, JavaScript, C++, C#, Rust, Zig, or Lua. They all compile to the same engine; the language only changes how your code is spelled. Switch anytime. How it plays Your program is bound to each tower every tick — me is the tower, me.enemies_in_range is what it can see, me.shoot(target) pulls the trigger. From there it's all you! The closest enemy isn't always the most dangerous one — so the naive shoot the first thing you see script will always get you started, and never win. Better algorithms beat more towers. Features - Code-driven combat — a real (but safe) interpreter runs your script. Clear, line-numbered errors, because debugging is half the genre. - A teaching campaign — a seven-stage tutorial walks you from your first shoot to full for-loop swarm control, introducing each threat one step before the tool that beats it. - 13 campaign maps across three tiers. - Easy / Normal / Hard — harder modes are tougher and longer, pushing you into scaled freeplay for the medal. Earn up to three stars per map, including a bespoke coding challenge that rewards a genuinely better algorithm, not just more gold. - Ten distinct towers — Arrow, Cannon, Tesla, Sniper, Frost, Venom, Support, Mortar, Chain and Detect, each with its own API: slow enemies, poison them, buff allies, lob splash at a point, chain lightning through a cluster, or reveal camo for your other towers. - Eight threats to route around — fast Runners, flying Flyers, armored Brutes, camo Shades, swarming Spawnlings, self-splitting Broods, and the nested Titan boss. - Build and share your own levels — draw a map, draft its waves, and share it with a single copy-paste code. An auto-balancer certifies every level is beatable and code-mandatory before you play. - Sandbox mode — infinite gold, every enemy on tap, hot-swap your code live. Prototype a controller, break it, fix it. Everything is deterministic, so a script that wins today wins tomorrow. Write once. Compile. Defend.
