I think this could potentially be a great way to add more content to the game without needing the devs to take time to make brand new bonus levels, since as it stands there are barely any of them. There are tons of levels on the mb that could make excellent additions to the base game (Neo Palmtree, Lilac Conservatory, Gigalopolis, Peak Waterfalls, Azure Paradise, and countless more incredible community-made maps). The only potential issue I could see with this is that most of these levels use music taken from other games, and they'd likely need original tracks in order to fit in with the rest of the game's levels, however, there may be other issues with adding community-made levels to the base game that I just didn't see. Anyways, If you have any opinions on this idea, Feel free to drop a reply, I've been thinking about this for a little while and was just wondering what the general community would think about this sorta thing.
