Having played many of the top SM hacks here, this is the one I come back to the most often. It's highly replayable with a second quest, and configurable randomizer.
My only two gripes are Spore Spawn and the Screw Attack puzzle. There should be some clue to solve the puzzle, unless I missed it. I ended up having to look it up.
The new items are really fun to use, and make subsequent randomizer playthroughs really interesting.
I don't think it's farfetched to say that this would work as an official release.
