good graphics, bad story
Good graphics, bad story. Not really funny nor surprising, the story (BOY MEETS GIRL) has been done a looooooooooot of times. Also, interesting how little time it takes to turn from stranger to lover... or at least kiss-able person. But okay, enough of the story, I think you know that wasn't the strong point.
Graphical style is quiet nice and clean, I recommend you stick to that style and maybe keep the picture a bit more in motion/action in the future if necessary. I liked the change to chibi-style. Strongest point of your entry and giving you the most points.
Sounds are "basic". No sound effects however (but they might be taken out during the calm music for artistic effect) and the voices were... bad? Sorry, didn't sound very in-situation or anything.
Also, after the squeak, how about immediately showing the unwanted guests for an even more surprising moment?
Compared to the really great entries on NG, this isn't more than 5 points. But keep on making flash movies, you're on a very good train. :)
