The basic premise is that you have to work out why no one is home when you arrive. The abandoned house is beautifully developed, with most objects being interactive. You can open all the cupboards and drawers and pick up most things. But you don't collect objects and solve puzzles like traditional adventures, you simply gather intel from each room to piece together what happened. There is lots of reading of notes and letters to do, and listening to the thoughts of the sister which are prompted by touching certain items. At first, it feels rather aimless, and I got to a point of not knowing what to do next and putting it aside for a while. But once you get access to the rest of the house, including the basement and the attic, the story moves into the final phase. It was worth persisting with, as the story was interesting and the ending was unforeseen. Overall I found it enjoyable to play, and loved the visuals a lot. I also loved the fact that there was no combat or time limits to interfere with exploring the house and discovering the secrets, unlike many games.
