This story reminded me a lot of "Where the wild roses grow" a song related to a man murdering someone he loved and giving her a rose. While also putting her body in a river. Anyhow off subject. About the Point and click.
1. I was impressed at the beginning the lightning and the soothing music kept me interested. This point and click has some unique aspects to it. A great deal of flow was put into it and the little effort added with the rain was gorgeous.
2. A problem I did have with it was that although almost all the chapters were fast enough sometimes I felt like the pace was a tad to slow. Even more so when I played again so I could see the second ending.
3. The concept of bringing a killer into the story was interesting but I felt like maybe a bit more could of been added. It would of been nice if there were more choices rather then just the interactive clicking. Like to choose if you could not do certain things expect for the ending.
Anyhow in a way you've done an amazing job at adding atmosphere and giving a sense of depth I just felt that in some areas it was lacking. Nice job anyhow.
