Internet Search Party: Find This Game, Please!

Now that I have somehow managed to grab your attention, I need help looking for a certain flash game I haven't played in years. I can't remember the name, hence my inability to find it, but I can describe parts of it. Here are some things I can remember:

1. It involved a man that is extremely lonely and is telling you his life story.

2. He had a wife, who I believe was named Katherine.

3. At the end of the game, it was revealed that he was actually in a mental hospital because he killed his wife and buried her in the back yard.

4. To make it through levels, you make shadows of yourself that you can stand on/move with.

5. Green and red platforms, some which only the shadows could go through.

6. All the levels ended with a flower.

7. At one point, you had to play as both the man and his beloved wife.

Anybody who could help me find it will win forty two theoretical dollars and an across-the-internet air hug, as well as much respect for figuring out the game from my shitty description. Thanks in advance.
