I... actually liked it.
At first, I thought it was a cheap SMBZ rip off... and I was right, actually. But, how it was executed was pretty good. I would try to stay completely original, though. I mean, even the text boxes were done similarly to AlvinEarthworm's...
Im trying to be constructive as possible, so on the upside, the animations were fairly well done, the plot is nice, and I did enjoy the overall result.
Summary: My ONLY real problem with this is that Im seeing too many SMBZ rips. Despite that, this is the only good one Ive seen.
Nice work, and 4/5 8/10
