Well...
It's okay. It passes the Blam test, but just barely. Here are my notes:
1) Either make the background bigger, or make Ness smaller, because he's way too big.
2) That's not Ness' house, that's Pokey's house. Ness lives in the other house.
3) Cliff scene was funny, keep it just the way it is.
4) Make the text scroll faster than people read, because it takes too long.
5) Clean up your spelling and grammar. If you have to use 1337 speak, only use it in one place.
6) That "a while later" thing was crap, because it was obvious that you didn't know how to get him to the arcade fast. Try a quick fade out/fade in, without text, instead.
7) Even if it's really dark, show a really dark arcade background.
8) Wtf.. foot? Hilarious. End the movie right after Ness gets squashed. It's funnier if he doesn't say anything at all.
