This game shows, like Stone Harbor, the power of a great story mixed with good physical and visual interaction. Both games are strongly linear, with fewer interactions, but with a great effect.
Ash tells the story of the death of the authors mom, a lingering death in the hospital. There are some interesting choices in the story with subtle effects later, but it's mostly linear. The beauty comes from the tight writing, the smooth visual effects, the appropriate font, and the way that the choices seem to reflect thought and intent more than actual decisions. You are choosing how to feel, not what to do. This worked well for me.
I finished both times with goosebumps all over my arm. This game is on the opposite end of the also great Cactus Blue Motel in terms of world model and interactivity, but both are great. Neither game resembles the super-branching wild stories that the lower-placing entries have. I love this game.
