Once again, I had to reduce the BG size, as that consumed more tiles. Still, palette 3 is easy to edit, most of FG1 is safe and FG3 is free.

Anorakun's notes: WARNING! This backgrounds uses all of the FG2, BG1, BG2, BG3 slots. Also a small chunk of the FG1 slots. Incompatible with moon, diagonal pipes, horizontal pipes, vines, clouds, bridges, bushes, nets, triangles, cement blocks, outlined blocks, goal signs, and etc. Use at your own risk.
Recommended BG Scroll: None, None.
Preferably with Layer 1 FG Scrolling as No Vertical Scroll.
This one got close of being rejected, but since you did some effort to save FG1, I let this one pass. Although, I don't recommend that beginners try to use that. Check the description to see what tiles were sacrificed. It's possible to make a level using this background, it will just require some creative thinking and etc.
Attention, users. To use bullet blasters, you may need to use some space from FG3. To use water, you may need to use a tiny 8x8 from the FG3 slot too. Same can be said about doors, although, a custom graphic of door would make more sense with this graphic, since the vanilla one may clash with the background. This graphic gets a pass because the users can use blocks and vertical pipes. And since the FG3 is free, it's possible to circumvent some of the issues. I warn again, this background is not user friendly. Use at your own risk.
