Thanks for your consideration
Just backgrounds for each of the 14 settings in the game, haha.
They can be tileable or otherwise, and if not, long enough to scroll down a little bit.
The frame is 360x480, and wider frames can support parallax scrolling, I guess.
As well as the backgrounds themselves, miscellaneous things such as stage objects (like buildings- one appears at the end of Stage 1-2 and serves as the setting for Stage 2-1 and 2-2.)
Stage 1-1 is a city on another planet.
Stage 1-2 is a desert wasteland (although I already have this one)
Stage 2-1 is an airplane missile silo thing. It's location is noted in-game as "Hidden Rocket Base."
Stage 2-2 is "Executive Core of the Base" and is where the rocket leader boss is fought. I thought it'd be hallways or something.
Stage 3-1 is a laboratory-ish setting.
Stage 3-2 is a storage facility under the laboratory at the bottom of the base. Full of things like boxes.
Stage 4-1 is in underground caves.
Stage 4-2 is in darkness, because it's even deeper caves. There's a gate at the end of the cave.
Stage 5-1 is in an underground city called Madness. It's like the capital city of Stage 1-1, except twisted and broken.
Stage 5-2 is named "Inside the Recesses of the Mind at the Core of Helios," so I thought trippy acid background would work.
Stage 5-3 is where the True Final Boss is. But you're still in the center of this planet, so lava? Rocks? Trippiness?
Extra-1 is in space.
Extra-2 is in the Outer Ring Fortress from Lunacy Star 1. The ORF being a large mechanical colony thing floating in the depths of space, so the background should be somewhat indicative of the Death Star.
Extra-3 is in the inner holding of the Outer Ring Fortress. (It being shaped like a giant sphere.)
Everything is up to interpretation, of course.
