Yeah... You have to improve your level design there a bit. It's too abusive, what means, you used lots of enemies or hurting elements in a little amount of space, and the level got too hard. And the way you made the level itself, I didn't like it at all.
Now some images to specify some problems:
Not too important, but a good tip to improve your english is not start all words with capital letters.
Here's what I'm talking about: it's too abusive for a level start. Too many enemies, too many tiles. A level start must be as simpler as possible. Btw I got hurt by this football in the first time I played this level.
If my blue block stock finishes up I get stuck here.
Not sure if it was in intention, but this lava doesn't kill, just hurts (and the spike top walks in it), what I found odd. The palettes of this part are odd too.
More oddness: upside down lava. But that's not the point. This just made this level awesomely hard do beat without get hurt. Take care with the level difficult.
Firstly, this palette is just white and looks empty. And it took a bit of time to I figure out that these trunks are solid.
Now reading your message... I couldn't get in the castle, but don't take the coins for don't die doesn't sound a good idea. Or maybe does, it's tricky... Anyways, you could use invisible question blocks instead (but still player can die if the POW time gets over. Take care again).
A bit of cutoff, eh? Plus in this part it was hard to figure out what's solid and what's not.
This pipe doesn't work. End of game? o.O
Good luck if you're going to fix this hack. I expect much from you.
