Well... the game isn't over! Best play for both sides would, I believe, see the top white group and the top black group alive in seki (that is, neither can put the other in Atari without being captured). But it's not impossible for one of the groups to capture the other.

I think it depends who's turn it is. E8 seems to be the key point; black first kills white, white first lives in seki. Or am I wrong?

It's w's turn, but he needs to play on the right side first, actually, or else W dies on both sides after b gives Atari.

Lildude512, it's easier if you post the game in SGF, like this:

Yes exactly! (but it's called "seki" - sente is when you make a move and your opponent needs to respond) Even if both W groups live, W loses the game, it makes sense that W resigned.
