It's just me trying to make things look as good as I can in a 20 year old game engine :)
I don't think there is a name for it. I included some special shaders like the posterizing effect and non-filtered textures to give it a 90s aesthetic. I guess it is kind of like a colorful boomer shooter style, but with exploration as the focus instead of combat? But I've been working on it since 2013 so I was not trying to make a boomer shooter, as the term did not exist back then. I think the 90s thing was something that was bound to come back in one form or another.
