So playtesting quickly led me to solve running through a forest without trees getting in the way. And they get in the way.

So of many attempts and other workarounds, this became the best of all worlds. It works. It's cheap, no fps drop, but then again, all the trees trunks, branches, grass and other foliage use this. Something I could optimize, sure.

Moving a little closer and the tree dissolves a bit more.

Welcome to the first world, the Ancient Forest.

​You start in an area of the forest that's open with smaller trees around, but as you venture out, the forest gets thicker and larger trees replace the smaller ones

Dark branch branches and trunks from vertex color test :'(​

Getting into the thick of the forest, large redwoods dominate the land with grand oak trees in the very back. They also serve as the "edge of the world".

Caution, the following contains developer talk:
This first world has been the most work, setting the ground work for procedural levels.
It's been a lot of...Testing.Profiling.Optimizing.Color Balancing.Repeating.

You may notice some white "things" in a couple pictures. Each level has crystals to draw power from. They are white because it's using a new refract shader. Although the old one was nice, the new one works with depth fog and is cheaper! Hooray!

Ouroboros means "tail devourer". It symbolizes the cyclical nature of the universe - creation from destruction, life out of death. In alchemy, it stands for continuous renewal and the harmony of opposites.

The story:
Ouromancer is the bringer of life and death, a continuous cycle, where even they must be reborn.
