Animated movie about an online social game

[3DGlasses]

Sorry but I only watched the trailer, I can't find it anywhere on the net.

It's a story of a boy who plays an an online game (an online communication game, I don't think it has any battles, I'm not sure). He has 2 friends, I think. 1 girl and 1 boy, I think the girl is older from him (or taller //I'm not sure if she's a friend or sister of his. Then the game itself wants to merge with the real world, and they're trying to stop it.

I'm not sure if its made in Japan (I can't remember), but the draw is like "5cm per second". It has a 2D/CG concept.

I don't think it has any connections with any anime series.
