Controls Orbit: mouse left click and drag.

　　Zoom: mouse wheel.

　　Space: generate a new level.

　　UI definitions - Left/Right arrows: changes the type of modules.

　　- Generate: generates a new level with the current stats.

　　- Seed: a specific seed for the random state.

　　- Random: will apply a random seed for the next generation.

　　- Map size: x/y/z level dimensions

　　- Divide: will apply multiple wfc dividing the whole level, for better optimization.

　　- Process: Activate it to see the whole generation, step by step.

　　- Speed: the process speed.

　　- View module possibilities: the wfc algorithm starts with all possible modules for each cell in the level. The whiter the cell, the more modules it contains.

　　- Backtracking: the generation may result into a cell impossible to collapse (it has 0 possibilites) and then it creates a red square. With backtracking, it will return to the last state, continuing the random generation from there.

　　You can find a simple implementation of the algorithm, (part of a Udemy course I'm creating) here: https://github.com/guillemsrr/WFCourse. Currently it will be in my native language (catalan) let me know if you'd be interested in a course in English!
