Edit: I see some great DS rips there which I haven't seen much of. It makes it more original. Great so far

Well, I couldn't get past the Piranha Castle because of a nearly impossible jump underneath one of the Mega Piranhas.
I like your graphics and enemies a lot, but I think the level design could be better. More power-ups would be awesome, too. There were several places where I could not pass without getting hurt, which seems kind of cheap.
However, if you are making this a super difficult hack for extra players, this might be what you are going for. So, I don't know.
I think you're off to a great start, but there is room for improvement. My main suggestion would be to vary things more.
It would be impossible for me to play this without savestates or rewinds.
Goddammit, the custom sprites don't work for me! They just stand there, like pictures. They don't move, and don't interact with Mario. I've had this problem with Game over and Stranded, but Brutal Mario works perfectly. Yes, my ROM is clean.
