Light (and darkness) will be an important part of Cavery. I want the player to feel small and vulnerable; most of the screen will be covered in black. That's why I'm working on a 2D lighting system. It's based mostly on shaders at the moment. All rendering is made by libgdx, of course!
That's the visible geometry (not covered by shadows):
I forgot to post it here, but it's official: I'm working on a new game! Some random keywords: cave exploration, darkness, vulnerability, suspense, equipment, discovering the unknown. I'll call it Cavery for now. Keep an eye for updates!
