This is well-written and engrossing. A clickable twine text game, Solarium has an interesting alchemical system which is quickly grasped through exploration of the narrative. As you progress through different memories, you obtain new story paths, and part of the fun is in speculating which will lead you to which.
There was only one moment where I worried that the game may have a dead end, early on, when I had gone through what I thought were all my options in remembering the story through alchemical reagents. I quickly realized that I simply was missing one of the options, and hadn't realized it was clickable.
Well-written, engrossing, and with an interesting ambience, this game is a mystical take on the idea of a nuclear apocalypse. The action mostly takes place in one room, as your character relieves past experiences that contribute to your understanding of what led to the apocalypse, and the limited role you played. The denouement is satisfying, and leaves you with a real choice, shaped by your perception of the text you'd just read, instead of by your collection of macguffins and plot points.
