I'm pretty sure that I messed up a lot of things opposed to the way they should be done.
However, I found a work-around to have the levels play in order. But I don't think they should be that way. The levels.nxmi file is missing altogether for some unknown reason. I tried to make a new one, but wordpad won't allow that file type.
Ranks won't work for me either. So what I'd like to do is see if anyone can help me to correct these issues. This way we can get a demo released for feedback, etc. What I will do is send the link to the download file and someone can take a look at it, please, and see what I've done wrong with it all. There are a whole lot of styles that I'd like to be gone - plus over 33,000 files along with them. I'd like to have only L1, L2, L3, and SMS Sega styles only. What happens when I delete the others? Well, I get an error message and cannot play the levels.
I'd like to kindly ask for some help. It would be great to know what several things I've done wrong. But the plus side is every level in the first rank is finished, there are 20 of them. Play them if you'd like. I plan for two ranks with 40 levels total, 20 in each rank.
I am not good at the other particular things outside of level design, I'll add.
