The game is a series of 3D puzzles. You control a character using the ordinary 3D FPS control scheme. Nothing fancy. But there is no combat. None. Some puzzles require some action, like running an synchronizing with other moving elements, like elevators.
The difficulty rate is really nice. At the beginning you face easy puzzles. Eventually one is harder, to keep you interested. Then a new tools or functionality is presented. And the cycle repeats, now mixing the usage of the tools in the levels.
The visuals are super clean but yet super nice. It allowed me to play in my notebook with any reservations. The whole universe feels right. The UI is super minimalistic.
The story is presented thru a inside or head voice, in a God-speaking to you kinda way and thru computers and holograms. Most of them does not clarify anything, but just expose someone’s opinions and points of view. It is up to you, the player, to figure out what the hack is going on. And it is deliberated dual, in the way that there is no one truth to the story. Every player will experience it in a personal way. The whole presentation is a follows the introspective and philosophical themes.
The game is a blast. I struggled in some puzzles but most of them are doable. Some extras are given for those that keep the super hard out-of-the-box puzzles. I saw the solution of some of them on the internet, and my mind exploded. They were super bizarre. I felt that just finishing the game and doing one or other extra puzzle would suffice. But I enjoyed every moment.
And also, I saved the game just before the final moment because I wanted to experience the multiple endings of the game.
Totally recommend it.
