The end really made this cartoon.
This one was too short in my opinion. Frankly I think you should have just made part 1 and 2 one movie (Yes, I saw part 1 just before watching this one). However, I'm sure you had your reasons (Probably file size). Anyway, the end was really funny, where he blasted Toad. Otherwise, this isn't the best sprite movie out there, although it is not bad. I'm sort of reviewing both movies in this review, as it really should have been one movie. Anyway, this mostly suffered in it's story. It really wasn't much more than Mario running through custom levels, which is fine, it's just that it really wasn't that impressive, nothing really all that interesting happened. Also, it was kind of annoying how everytime there was a fireball, it hit a bad guy (I'm talking about the first one now). The second one was pretty much the same thing. All it was was a fight scene, and not a really interesting one either. Like I said though, the end was pretty funny. Anyway, that's it. You certainly have potential I think, you just need to work on your ideas.
