+## Made with Claude Code
+The game was developed with the help of [Claude Code](https://claude.com/claude-code), Anthropic's AI coding assistant. The small pixel-art mark next to the note on the title and login screens is a rendition of the Claude Code logo. Claude, Claude Code and Anthropic are trademarks of Anthropic; the mark only credits the tool and is not covered by the MIT licence of this project.

## Everything else
Code, procedural graphics and game design: the DungeonCraft project.

# DungeonCraft
+> **Made with the help of [Claude Code](https://claude.com/claude-code).** The code, graphics, texts and
+> documentation of this game were written together with Claude Code, Anthropic's AI coding assistant.
+
An original dungeon building & defence game that runs in the browser (Rust + [macroquad](https://github.com/not-fl3/macroquad), compiled to WebAssembly).
Dig out your underground realm, claim the portal to attract creatures, keep them fed, rested and paid, fend off endless hero waves that adapt to your army – and finally destroy the Hero Gate.
