SMW content - Need for Speed (YES, I DID ALL THIS IN TWO DAYS)

''I've started another hack friday for this C3, to see how far I will get and for the sake of having more content to show. Wish me luck.''

Seeing how C3 is mostly based on SMW hacking and the like, I decided to make an attempt at a C3 submission... from scratch. Yes, all of the level design for the two levels was only done over two days. So again, I managed one level per day, on top of the drawings I did for my drawing thread.
The title is temporary, but self-explanatory: the hack had to be assembled as quickly as possible, before C3 ends. I was hoping to include a third level by Monday morning (a ransacked castle), but time ran short.

I'm surprised by how easy this was.

That one green parakoopa that turns around to get in Mario's path when it touches an upside down piranha plant is just brilliant. The level design in both levels is interesting and good, especially in the second level.

After the midway of Life in Motion, one of the eater blocks doesn't spawn about 75% of the time, making the level impossible.

Well, I don't know what to say.
I can honestly recall testing this enough and eliminating enough sprites surrounding the blocks so this doesn't happen. Which emulator were you using, and more importantly which set of blocks wouldn't spawn?
