Hi Nacritico!
I accidentally watched the loop 3 times <_<....
It wasn't too good to tell the truth.
Music: 0/10 *none*
Graphics: 4/10 *Sprites, which isn't always bad, but it wasn't the "excellent" sprite graphics. For example, the dirt when mario landed at one part was not a sprite and didnt go with the theme. Some pixels were the incorrect colors too. The Mario running with transparent ones behind was nice, and so was the repeated slow motion parts.*
Story: 0/10 *none*
Originality: 1/10 *Mario attacks shells, big woop*
Of course, it was just practice. Practice is supposed to make you better.
Just giving you supportive critisism,
Pauzle.
