Okay...deadline is approaching...time for my final update:
Nine Inch Fireballs
BTW a lot of people might be telling me that the clapping chuck part is just taken from kaizo. So my response: I modified it. In kaizo mario, the clapping chuck only had 3 tiles to jump, so he never got to the height of his jump. Hence, he did not stay in the air long enough, and the timing to get under him was unfair. In my hack, I raised the roof one tile. This means you have more time to get under him, and this 1 tile is the difference between kaizo and non-kaizo (I had to point this out since I don't want my level to be disqualified for being kaizo. I will let you know that I have tested it, and managed to do the whole thing without savestates or rewinds, though I made a savestate at the midway point so I would not get a game over)
Also, take the time to read any message box that comes your way. One of them is not useful, but the other three will be very useful. Furthermore, I will point out once again that there are 16 hidden lives in the level. 7 before the midway point, and 9 after. See if you can find them all (I did not test getting the hidden lives savestateless, the path to the hidden 1-ups and 3-ups is hard, and I used rewinds when testing it, so be aware that they are optional)
Finally, watch the entire credits sequence, up to Yoshi's House.
