Decided to try to make a stage based on Ridley's boss room (over Skyworld) in original Metroid, Metroid Zero Mission and Super Metroid. Right now, main platform is finished and background is nearly finished. Still no extra platforms like on SSB4 Pyrosphere or at least 2 extra platforms.
Both lava and those green lights are animated. No hazards. I plan on adding both intact and broken pillars in the background, like in ZM and SM. I'll try to not use anything from Norfair except for maybe pillars and/or doors. None of the stuff used here is 100% custom (i can't do this kind of stuff), but im not stealing anything from someone else's work.
Right now, this thing lags the game. This is something that is easy to fix since its mostly because of the junk you wouldn't see without zooming in enough with hacked camera (for example, there actually is normal and pretty detailed floor, but its hidden under the lava all of the time)...but i don't really have tools for that for now.
EDIT: Its nearly finished:
Just need to fix few things like green lines and materials.
