Hello, I'm a fellow player who found this gem a few back, and I also appreciate your review. Though I do have to disagree on one point here, I noted, 'If Tamara needs to go back in time to save humans from extinction, then why does she and other humans exist in the future, before she goes back in time?' Have you heard of the loop theory? We exist BECAUSE she went back in time, it makes a loop to the present, unless that loop somehow breaks. Time doesn't flow congruently, even if she is in the process of saving it she should be in a future in which she had already saved it. Think of counterparts. There could be different timelines and worldlines, I like to call that open ending which leaves it for us to decide and imagine! Just my thoughts, and maybe something to think about. Perhaps this explanation would fill a plothole for you? Let's all enjoy the game!
Thank you for sharing,
