Lumenrift: tower defense
A strategy game WhiteBlackGoose built with Claude Opus 5.5. Copy the exact prompt free.
WhiteBlackGoose built this with Claude Opus 5.5 and shared the full prompt on GitHub; it is quoted below word for word. Something has torn the world open. **Rifts** bleed shadows onto the land, and each night more of them crawl toward the one thing they hate: the **Beacon**, the last light, burning in the middle of the map.
The prompt
Make a tower defense game (playable in web, I'll give you the github repo to commit to later, for now you can init a normal git repo). Basically a single game always starts with some kind of central building in the middle, and as you progress, you can buy more advanced stuff. You're attacked by some kind of enemies, that grow in numbers over the time (should be well-balanced to keep it interesting). And you keep defending by installing different kinds of weapons, traps, walls, whatever. I'll leave up to you not only the programming part, but also the creative part and the assets part - so you gotta stay creative. You can create commits, and you can also spawn agents to help you. You can also test it if you can. If you have some questions it's time to ask them now, afterwards you'll be working on your own
