Boring and very very long. I was like those silly travellers that asks "Are we there yet?" to the driver because I couldn't stand the travel anymore. This hack conveys more or less the same feeling to me.
The design is linear... terribly linear. You can count those few levels with altered design on your fingers; the rest is pretty much going straight avoiding enemies. Something that annoyed me in particular are the blind jumps, which in the first half of the hack are very frequent. Around the 6th world, I started getting very bored of the same design over and over again. Overall, it's not a hack I'd recommend. It would be good for those newbie players of SMW, atleast the difficulty curve has been handled decently here.
Aesthetics is pretty much the result of many games' GFX thrown into a washing machine. Not that it's necessarily bad, but the style changes too much, even in the same level sometimes. Atleast it's well varied from this point of view.
-For some reason, the hack starts at the last world. If you take the star warp, you get at the beginning, at least.
-Sprite Tile Limits issues, especially in castles.
-Some massive slowdown occuring in a few levels.
