Double post!
It's time to bump this thread for the last time, because Christmas is coming, and I've resumed work on this hack to finish the 2 remaining worlds!
So far, 2 levels of world 4 are finished.
Level 1:



This level has two variations of rideable falling leaves. The white ones are safe, while the blue ones are so cold they hurt Mario if he touches them.
Ignore the time set to 0, this has been fixed.
Note that world 4 currently doesn't have a name.
Level 2:



This level doesn't have any new enemies, but the Bullet Bills that freeze Mario from the third castle come back in this level.
I've also changed the status bar's font and the item box graphics.
