Kind of nice.
It's a cute little game with nice music and graphics, and the "friends" are varied and interesting enough to keep you searching for them.
But in the actual game, all you end up doing is randomly choosing directions. At first I thought maybe it was just a maze where every room looks the same, but no, it's apparantly more like the Lost Woods in Zelda. Without any way to know where to go, you're not so much playing a game as you are idly pushing the arrow keys.
Though honestly, even if the exploration WAS better, the gameplay would still be boring if all you can do is walk around identical screens. A more varied and more interactive world is in order.
