Ehh, not that good. The design for the most part is kinda bland and the hack never seemed to pick up. I do consider this to be easier than smw returns 1, but a bit boring imo. The secret exits don't really help much either. You will not be able to find them unless you are the creator of the hack. There isn't a red dotted level anywhere, so you never know where the secret exits could be unless you look at LM (had to use recover LM because this hack is locked).
This was probably mind blowing for the time because of all the custom graphics and such, but nowadays, it's just a museum piece more than anything. I personally wouldn't recommend this, unless you like to go through old hacks out of morbid curiosity
