Might be that the staff just hasn't gotten around to testing and approving it yet--one of our Level Moderators temporarily doesn't have access to a computer, and the others might simply be busy. For future reference, here's a quick way to check if your level was properly submitted:
This is the condensed SM63 level list. (Find it on the main forum page at Level List --> Latest Levels --> SM63.) You can see that your level was submitted to the approval queue, since "8 Frosted Red Coins" shows up in the list. But the link leads to a nonexistent topic, and the
full level list doesn't show your level. If that's the case, then you don't need to submit a second time; the mods just haven't been able to approve your level yet. If you've been waiting a long time, or if you have other questions, then try
PMing the Level Mods, or join the
Discord chat and get their attention by typing "@<Username>".
By the way, your English looks fine. You're welcome to practice it here as much as you like. :)
