You could have just put it in your filebin, that way I wouldn't have to get an account at 4shared just to download. Literally the only reason I got one was to download it. Also, I'm not sure what language you speak, so I'm sorry if you can't read my English.
As for actual feedback:
I don't think just precision jumps like so alone would qualify as Kaizo.
Run under Chuck trap #4487787
This trap has been used too many times to count.
I think I see what you wanted to do here, but I don't think the fireworks look quite right, and they make Mario disappear.
Also, you might want to take up overworld editing, or at least disable access to Nintendo's levels if you only wanted me to play this level.
Some parts toward the first half felt Kaizo challenging. The second half, not so much.

How am I so creative? I think taking walks might have something to do with it.
Every single level I will ever make in SMM2 will be easier than Ultra Necrozma.
