Super Mario Maker level sharing thread

Thanks to some generous players, I've managed to receive enough stars to raise my upload limit to 20. Anyway, my next course is all set to go.

3-3: Flight of the Buzzy Beetles
326B-0000-003F-B13C
New Super Mario Bros. U

This new course is probably tougher than my last set of courses, but the difficulty is still fair in that there aren't any hazards around; it is also my very first auto-scrolling course in Super Mario Maker. The main challenge is just trying to land on the flying Buzzy Beetles, which are the main element of the course; some of them do have Goombas or Piranha Plants on their backs though.
 
I have reached my upload limit. I just need one more star.

Okay, I uploaded two more long levels. One classic (if a little hard, but there's a trick to make it faster), and the other... check for yourselves, the title says all :wario:

Name: Battle For The Destiny Of Earth
Theme: New Super Mario Bros U, Airship
ID: C697-0000-003E-5DAF


Name: Who Wants To Be A Billionaire?
Theme: Super Mario World, Castle

We are making our own SMW game and here is World 1 for you to enjoy. Remember this is supposed to be World 1 so don't expect anything too hard. I suggest playing through them in order to make it feel like an actual game.

The castle stage has a unique boss battle.

3-4: Conveyor Belt Castle
AEEE-0000-0043-2B78
Super Mario Bros.
https://miiverse.nintendo.net/posts/AYMHAAACAAADVHkcm3XD_A

This course focuses on the usage of the conveyor belts. Bowser Jr. is giant-sized, while Bowser has a Hammer Bro on his back. There's also a hidden Mystery Mushroom, but if you're going to try to complete the course with the Mystery Mushroom power-up, you will have to tread more cautiously than if you were to use the Fire Flower power-up; this is especially true once Bowser starts spitting his fireballs at you.
 
My second course:

Name: The spiky castle
ID: 71F4-0000-0043-6954
Game theme: Super Mario Bros. 3

By the way, nobody has beaten The ghost house of terror yet. :P

I spent a ton of time on making this one work, I'd appreciate it if you guys would play it. There's only one shell, hold on to it.
