Considering it's an older Hack it proves how well Hacks can be designed back then. Well, some levels are a little too long and there are some exaggerated difficult parts (like the part with the Swooper Ceiling and Big Bertha combination), but it makes more interesting to keep on playing.
Seems a slightly edited version of a previous version. While the author did fix some of the bad things and managed to make the hack better, the design still kept almost the same. I'm not really a fan of it, it's mostly good, but sometimes there are really frustrating parts, (like taking certain pipes brings you back to the beginning of the level, the need of item babysitting for a whole level, etc) that don't make it totally enjoyable.
The changes are mostly in the aesthetics, the author used HDMA and better graphics, if compared to the old one.
