This exact thing doesn't 100% fit into any levels, but my main idea was making giant terrifying circuit-boards, and that idea's in the game.

I'm concepting a level where you fly through a giant machine, and the last couple arts I uploaded are different ideas for that. The final thing is probably gonna be something that combines what's good about both. So like... foggy metal cavern lit up by streaks of circuit-board?
Stay tuned, I'll make a third one.
