This game thrives as the quintessential Romhack to play after Learn 2 Kaizo. It truly takes the training wheels off without sending you down a dirt hill.

The level design is great! Romhacks like this kind of thrive off of not being very sightread-able, but once you know how to get past each obstacle it really falls on you to perform. In other words, there's not many cheap deaths, and even the ones that are aren't really too bad. Kaizo blocks are part of the culture, of course.

This hack is what's convinced me that SMW has a way better physics engine than MM2. The amount of control you have is insane.
