The design idea is a NES MegaMan version of Super Metroid with the boss selection screen.
Also, I was thinking instead of pure black maybe Heather Charcoal could work too? I'm not sure how dark they are IRL but if this gets approved you could choose what you think would look the best.
I'll also submit a version without the names of the bosses written out in case you prefer that.
