This was one of those hacks that must've seemed revolutionary at the time for what it accomplished, but in this day and age of SMW hacking, it is really more of a museum piece than anything.
The graphics are pretty much what you would expect from such an old hack--lots of SMAS graphics and enemies reskinned into their SMAS 1/2/3, with a few other influences like Donkey Kong Country and Mega Man here and there.
The level design feels like it took some strong notes from Luigi's Adventure--as in, rather lengthy, repetitive, and very difficult stages that provide very little leniency to the player, and will frequently punish the slightest of errors by making you do all that over again. Do not expect to see Mario in his fireflower palette, as not only are powerups generally scarce in this hack (most stages only have two powerups, one if there is no midway point), but it almost feels as if the author forget that fireflowers even exist because there are several occasions where it is impossible for Mario to jump on top of the block!
The ASM pretty much falls in line with the level design, and while there are some really neat gimmicks like rising air currents, fluctuating blizzards, etc., they are often implemented in rather poor ways (especailly the blizzard levels), and end up being more frustrating than fun.
Overall nothing I would recommend unless you are looking for a hard hack, and even then there are much better ones in that department.
