Decent hack overall, some levels have some janky setups and sub-par level design (mainly the levels that scroll up without being able to see what's ahead), but other than that it is a fun hack. Would love to see a non-death counter version of the hack so it can run on SNES Classic.
Really good kaizo hack, I would say it's in the harder part of begginer difficulty, because of levels being mostly few seconds long. My favorite level is "the joy of kaizo" which is a recap level of earlier levels
I'm one that when I make my Mario fangames I take inspiration from people like you! My fangame from the use of SMBX is called The Legend of 39, as the name implies it actually tells the story of the song 39 by Queen so I will never take any credit in story writing, don't even think about trying it you will regret it. I love making games where Speedrun tactics are needed and you can find all sorts of "Cheep/Bullshit" deaths but I make my own games to challenge not just people like you but also myself! Thank you for making such an awesome Speedrun hack! Who knows, you might see some of my "insane" twists to some of the tricks from your hack in it!
