Let me start of by saying, I did not play the other two hacks.
Overall I found the hack to be pretty alright, however some setions just bring the (level design of the) hack down quite a lot.
My biggest issue is the difficulty curve. The first level was all fine, the second one as well
(other than the cheap hits by goombas/koopas just falling right onto you, leaving you with no time to react).
However the third level presents a huge difficulty spike that I found very off-puttting.
The difficulty comes from a few jumps being ten times harder than the rest. Examples being the required shell jump and the ~three following screens.
I have similar issues with the last level, especially with some of the tight jumps in the second half.
Other than that I really enjoy the art style and overall charme.
