There's no story to this one. It's just a collection of levels with varying degrees of vanilla-ness, ranging all the way from pure vanilla to I-Can't-Believe-It's-Not-Chocolate vanilla. Some levels even have custom music, mostly from the VLDC collections.
Is kinda a shame that's too short, otherwise, is a 5/5, my man. My only problem is that the second to last Big Boo (the one before the pipe leading to the exit) on the haunted hills (I don't remember the name) can trap the player when they go for the last Yoshi coin, forcing to lose your powerup/a live.
Decided this'll be the next full playthrough i'll put on YouTube. Looks like it's good.
And it is! Only problem I have with it is that levels feel a bit samey after a while. But I gotta say, this is one of the top hacks in terms of more basic romps to play through, and i'd definitely reccomend newcomers to the hacking scene to check it out.
