The Forever Cat stalks through this universe, collapsing it when the Others come close or shiny objects are too far apart. Will you end the Forever Cat's destructive cycle and help this universe's quanta join the multiverse?
You begin the story (again and again...) as a particle in a mass of particles before time begins, and as the story proceeds--I think--you become part of larger objects, including (depending on your choices) a dog or a human, in which case you take on their perspectives. The theme of the story is pulling together or pushing apart, whether that is particles attracted by gravity or humans drawn together as a family--or separated by death.
The concept has some merit, but as a game (or interactive story) it fails. In most cases, you are presented with a little text and then two or three choices, and in many cases only one choice allows the story to proceed, the other sending you back to the start. Once you've been through the beginning and handful of times, the only thing to do is click through the early choices on the sole path that allows the story to continue, in order to get back to the point that--maybe--will allow you to proceed. This is dreadfully dull.
Additionally, for all the writing has a common theme, there's not a coherent plot. An individual scene isn't connected with any other. There's no sense of progress, and you learn nothing interesting as the story proceeds.
I reached an ending (number 2 of 5, I believe), and I did play on a bit more, but I found the repetitiveness boring and the dead-end choices frustrating, so I didn't continue to seek out the other endings.
Play time: 18 minutes. Got one ending after about 10 minutes.
