Indie game devs spend hours manually designing dungeons or wrestling with complex procedural tools.
Create a simple dungeon generator with presets for different styles (medieval, sci-fi) and export options for Unity/Godot.
Sell to solo devs and small studios who want unique levels without coding everything from scratch.
Start with a web-based demo that outputs 2D maps, then add 3D and mobile exports.
Risk: Competing with free open-source tools, so need clear UX and niche styling.
