Name of a game which i used to play a long ago.?

I forgot name of a game.

I used to play this mobile game on my Sony Ericsson w200i. It was a maze game with a top-down view. There were two characters(both girl). One was supposed to stay under light and if she got into darkness she dies. While the other character was to stay under darkness. We can shift to other character anytime and can use them simultaneously to stay alive and solve the maze. We could step onto a platform to raise the gates/doors. I think it was similar to Playdead's Inside.

Thats all i remember. I hope someone can come up with the name.

Thanks.
