Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.
Removal reason: ROMs are absolutely not allowed for submission under any circumstances, as outlined in the "Do not submit illegal material" section of the rules. Submitting copies of already existing tools, including packs, is also disallowed.
We have a very strict no ROMs policy here. Please conform to it.
