***I did not look up any guides to any puzzles or dialogue options***

It took me as many hours as of writing this review to beat the game once, and with Elohim's ending (in doing ALL the puzzles in each of the buildings, and not ascend the tower, nor the DLC - Road to Gehenna). I actually did not receive any advice from any of the messenger's as I did not open any of the abodes throughout the game.

The approach to me felt like playing Portal, but fiddling with lasers, cubes, bombs, jammers and other tech you unlock along the way, and are included in combination on some of the puzzles as you go on.
The puzzles can range from "Oh, I get this" and finish the puzzle in a few minutes, to "Oh, this is more complicated than I thought, it's going to take me a moment" and have me contemplating a singular puzzle for 1 hour, figuring out the best approach. (or maybe I was too tired to wrap my head around how to do so X'D )

The philosophy side was intriguing to unfold upon, as it questions (as the storepage states) what makes someone/something human, consciousness and morality. Some of the other references the game makes also gave me a chuckle <3

I will be absolutely playing the second part of this games' series, but I need a mental break first.

I would recommend this game.
