There were some parts of this remix that weren't as good as Marta's though, so when I watched this expecting the most perfect version of the song, it let me down a little. For example, the voice of the goomba at the start just seems to cut abruptly into the next part of the song (the timing didn't seem quite right to me, and that kind of thing can really throw off the mood of the song). If the remix (mostly concerning the vocal parts) was a bit more fleshed out, I would consider this a 9 or 10.
The animation was nicely arranged, and crammed in a good amount of references to SMRPG as well. Overall it was a good flash for a great game, both entertaining and nostalgic. Good work to all involved, and good luck Chris on your future work.
