MM2 Levels for my kids feedback

Good day. I've been working on my level design and worked on a few for my kids to play. These are non-trolly, not terribly difficult levels. I've play tested them myself and tweaked them to death and I can't tell if they're any fun anymore as a result. 100 coin collecting challenges, first one isn't too difficult; pretty sure there aren't any potential soft-locks. The second one has a challenging platform section and a tighter time limit. If anyone could provide some feedback I'd really appreciate it. Not hunting for likes on it or anything as, if I make changes I'll need to re-upload anyway :)
