It looks pretty faithful to SMW, however I have a few problems with it.
While the level was decently designed, and enemy placement was well done, I do feel there were too many types of enemies thrown in without rhyme or reason, and I feel you could have made it more enjoyable with less enemy types. Another thing is the level didn't feel like it had a consistent theme. What I mean is the falling platforms were only used twice, and sections of going on a moving rope were quickly followed by enemies on springs. If I were to suggest anything, you should have sticked to the moving platforms and the hammers in the moving pipes, or two other themes.
Aside from these, I did enjoy the level.
