Some Levels I played:

Pure Platforms No Enemies
Gotta say I grew a bit bored and moved on to your next level. A flag at the end of the first section would have kept me going.
Charge! Shoot the Core!
This level was much better and was quite fun. The quick pace made it exciting. In the second part I would suggest perhaps a longer bridge to get into the clown car because I got pushed off and died immediately. Wasn't really a big problem since you hit the flag automatically though.

MTW 1-1
Great introductory level to your set
MTW 1-2
Difficulty ramps up a little bit and there's some fun secrets.
MTW 1-3
Easily the best of the three. I loved the little marks showing where thwomps were falling and the boss was an implementation I'd never seen before and it was executed very well. Awesome level.
This bookmark system is so awesome. So much easier to quickly play other peoples' levels. I'm excited about getting back and making new levels now too because other people might play them more!
Heres some of my previous levels if anyone wants to take a look:
