This is the first entry in a series called "My Super Mario Maker Level Collection" (will be tagged as "smmlc"), where I post new Super Mario Maker levels I make! These aren't scheduled, and there will be a random amount of levels depending on how many new ones I have.
Here are the first two ones I made!
