I was struck when starting this game by how lovely the visuals were. The colors were rich and vibrant and the style was kind of impressionistic, allowing some flexibility in how to interpret things.
Most of the game is a series of conversations with 'Elias'. I don't want to give spoilers, but I don't think that would even be possible, since the game is not definite about what's going on.
'Elias' looks like a kind of plant monster. The real Elias was your boyfriend, but this thing can talk like him and seems to have some of his memories and feelings.
You are someone living out of their car, where everything is, and no other person is visible anywhere in the deserted areas you drive through. It's just you and 'Elias', whom you've trained or asked to re-enact your past memories with.
The art, music and lyrics are haunting. I thought at first it would be a shorter, poetic piece, and thought it was coming to a close, so I was surprised when it went on for quite a while. The ending was transcendent in the literal sense, as it passed from clearly understandable phenomena to something more. I didn't fully understand.
The game is mostly linear, with some choices along the way that may have had story impact but felt more like (good) flavor. I felt like the goal here was to write a game that gave a certain strong impression or feeling of combined nostalgia and alienation, and I think it achieved its goal.
One thing that could have been nice would have been a way in-game to know how much of the game I had completed or a way to save (maybe there was one; I didn't know any UI) to ensure that I could plan to experience the whole thing at once. But it was a charming experience and I found it really beautiful visually, one of the nicest-drawn games I've played in a long time.
