This hack's idea is pretty nice. Its aim is to show to SMW newbies all the elements and sprites of the game. While an experienced player may find this a little bit boring, I think this one would be really useful instead.
Due to its nature, this hack's design isn't really a design, in most of the levels. They're small and very fast to clear (for an experienced player, that is). Although some levels do have some better designing overall, like the ones at the end of the demo, which are pretty fun to go trough.
Aesthetics are okay. Since this hack teaches newbies which elements this game has, the author used pure vanilla, not even custom music or sprites. It's well done, not much to say.
Overall, an useful hack, but may be boring for some players. 3/5.
