I reviewed your last movie and i can say-
This is ALOT better then your first. luigi kinda came from nowhere but it was not that outofplace. it looked like you worked hard. and make sure when your geting the swf. dont just use the swf that flash automaticly makes. go to file>publish settings>publish. thats what will lower your file size. and good luck.
PS. there was somthing weird about that hole. like soething behind it was have a seizer or somthing. lol. hope my last review and this one helped.
