Frigga is an all-in-one solution for procedural generation of tile-based levels.

Configurable Walker and Noise generators

You can choose from 2 different layout generators based on your needs. Each one is suited for different scenarios and come with reasonable defaults to get you started quickly. They both have many configurable options and a comprehensive documentation, so you are encouraged to tweak the parameters based on your precise needs.

Powerful Theme engine

An intutitive theme system that builds on the idea of Rule tiles while also adding many powerful features. The system handles both basic geometry like wall tiles and floor tiles, but also decorations and entities likes enemies, treasures, trees and much more.

Hand-made structures

Making random levels is fun, but what if we need to make sure that each level has a spawn location, a boss arena or a specific number of treasures? That is where the Structures feature comes into play. You can create hand-made structures and spawn them in a level using robust placement rules.
