Actually an approval system makes the judges review your levels, remember in Revived? half or more of the levels didn't have a review, with this system you WILL get a review
This doesn't seem too good, there's clash, cuttoffs everywhere, and bad design choiches, doesn't even look fun to play...
try fixing the clash and cuttoffs, maybe in screen 2 you should use the smb3 cave background for the land/cave part
