The bigger sins, however, isn't so much the lack of slopes, but the fact that there are object limitations, AND course length limits as well. Obviously, Nintendo didn't want players to be uploading ridiculously long courses, but only being allowed to place up to 2000 block objects on a course heavily limits how you can set up your courses.
Honestly the limits aren't that restrictive, I've only really been hindered by the block limit once, and even then the level I was creating was horribly complex. They only become a burden if you're trying to add multiple areas with doors imo.
Also, most of the limits are justifiable considering the lack of checkpoints. Like, I respect someone who wants to put effort into making an incredibly long, challenging level, but if I die at the very end then honestly I don't have the time or patience to go through it again unless it's a really good course. Less is more etc. etc.
