Anyone playing Mario Maker? Want to share stages?

Fun game this Mario Maker. Getting to create and share and play around with what is possible with the 2D side scrolling Mario format, from simple platforming stages to racing a koopa shell to a shoot-em-up to a recreation of the original Metroid to puzzles to solve, quite a lot can be done.

I, however, do not currently have the knowledge or the ability to truly make great stages yet, but I can still have fun trying. For now, here are three, from my very first stage, to another just trying out an idea of chasing an enemy, to one I'm somewhat proud of. Enjoy.
Take a spin first try: 95F3-0000-0034-99DE
Under and over: 815B-0000-0039-B1CD
Ganon Jump: 53E8-0000-0039-EDA4

If you have any to share, I would love to try them out.
