Details:

No external visual art was used in this project. All models are created from basic shapes in the Godot Engine, all textures are generated at runtime using noise algorithms and somewhat interesting math. Even the animations are done in-engine.

Warning:

It may seem broken when it starts, just wait a few seconds until it loads the level. Due to the method used to generate the snow effect and the large number of objects in the scene, loading it takes time, I'd expect up to one minute or more on lower end hardware.
