Just finished it and I can say it's a really cool immersive fps puzzle adventure game. I've been wanting to get my hands on this game ever since I watched Markiplier play it back in the day. It honestly felt like Half life but even way more! I saw it coming.. right from the start Morgan Yu is a Typhon himself. I saved each and every npc and chose to take Alex's hand.

To quote a youtube comment I saw

"When the game revealed to me that Morgan Yu's personality kept changing after each test cycle, a thought occured to me. My role, as a player, in this story is that my own personality is the latest version of Morgan Yu's personality. In this sense, for the first time ever in a video game, I was playing as myself in a very real way- my own personality and choices were canonized by the game as a part of the story itself.

This still remains true after the simulation reveal at the end. The "soul" that Alex had given that Typhon was truly the player's soul- my soul. That's why I took Alex's hand. I had resolved to uphold my morals and principles throughout the game, and I would continue to do so even if I was in the body of a monster, and even if I had to work with a man I clearly couldn't trust to save the world.
