Good job!
Considering the moving platforms - you should definitely consider when you want them to start moving. Especially if you have this many. Does it start moving when the player enters the level? When it first appears on the screen? Or is it triggered by something (for example a door opening)? Going with the first one can be very frustrating for the player, esp. if the platforms are slow and have a long path.
Additionally the two platforms at the end don't quite align, I'm guessing the issue lies in the two circuits taking a different amount of time to complete, so the situation where it's possible to jump from one to another doesn't occur very often. I don't know if this was intentional or not, but it felt very frustrating to play.
Take this as food for thought for your next work and assignments :)
