ending...
You were all warned that you get one chance, thats the way the author intended the game to be. If you don't like how you don't like the chance at losing then don't play? If you don't like 'artsy' games then don't play. Don't eat spicy food and give it a bad review because you hate spicy things and Behold: The spicy food you ate was spicy.
It's "realistic", sometimes you don't get a second chance, sometimes you lose something no matter what you do, sometimes you can't win. Life isn't always puppies, sunshine and rainbows.
That being said there are things that could have been improved. I managed to "find" a replay button so I tried out all the choices. You need more endings (die with bar girl?), more choices would have been nice, and more detail in the art should have been used for such a simple game. Car scene should be a cinematic and your character should move a bit faster.
I like this mostly because people got so worked up about it to be honest.
PS: I think Molly is dead when you're on the bench with her. Her eyes are closed so she might be sleeping, but you abandon her temporarily. Probably wouldn't do that unless she was dead. Would like author conformation, but probably won't get it.
