I enjoyed how the story came together, with each location blurb, and the gradual reveal of the AI's persona. I like the duality of the uncertainty whether the AI is hostile or if the AI is just trying to console the player. After playing, I think the AI might be the player's guilty conscious and self-forgiveness.
The only thing I'm left confused about is the transition between the three environments. I'm not sure if the player is just in denial about the facts surrounding the accident or if the player was trying to plan a vacation to heal but their mind started to wander and wanted to revisit the site of the accident.
If I were to give constructive feedback, I'd recommend a main menu or settings panel in-game that allows the player to toggle fullscreen mode and set volume. An accessibility option to turn off field-of-vision panning (moving cursor to bottom-left causes camera to slowly pan bottom-left with a delay) would be a nice addition too, since it can be disorienting.
