Interesting.
The story is good, the old gameboy animation is good, but I think you should have made a series of flash movies rather than a game. Sure it gives you the option to create the story your own way based on your personality, but it's still a pre-made story. It would have been more entertaining if you had made severral short flash movies about couples going through problems like this. But hey, that's just my opinion, isn't it?
Back to the game, like I said, the plot is interesting. It makes you want to play it a few times to see what different outcomes you can get. It really is rather sad that this kind of thing happens in real life too. Falling in love with someone only to realize years down the road that you may not have made the best choice. But, that's what makes this a good story; the realism. Good work.
