Awww yeah, good to hear! Fundamentals tutorials are quite important for me, still figuring out how to make them feel less tutorial-ish, and there's a lot more to come. Having those missions be available to new players helps me not worry about the arcade mode's difficulty very much.
The silver/gold medals are functionally the same, but since it's a cycle of 3 medals I wanted to distinguish each medal in the cycle visually a bit, probably needs some work. I'll definitely fix visibility though, common complaint.
