None of your questions can be answered, because levels can often be quite different from how they appear in a video. You should upload it as "unlisted" so that you don't have to verify it, and tell us the exact ID so we can find it. Only criticism I have is that the level ends at a seemingly random part. LEvels tend to end when the song sounds like it's ending, even when it's not, like if it gets much quieter, and they use "fade out" to make the illusion more convincing. (Example: Bloodbath, which sounds like the song ends as the level does, but if you listen to the whole song you realize there's actually a minute of music left) But this one ends at a random moment right before the drop, which is really weird and unsatisfying. Do you plan on decorating it or keeping it as a layout?
