Its quite a great game. I found it trough searching for tf games, but I stuck around for the worldbuilding. It has such a unique and fascinating power system. Its really interesting to see how it gets fleshed out and explained chapter by chapter. Its a pretty great mystery even when you get some elements of the world explained it just opens up more questions.
Pretty fascinating to see how a lot of characters need to operate on limited information and how they attempt to survive and cope with a situation way beyond their control and understanding. Really shows off the importance of cooperation and support, it probably wouldn't have ended well for each of them alone even if they had survived. Especially considering what happened to the characters who got in earlier.
Even the wills are quite fascinating how each of them developed their own ways and beliefs to live their unique existence. Each of them also usually having their own slightly different utilization of the power system.
