Overall, the game is fun.

Story is surprisingly existing, despite being rather short.

Gameplay favors stealth, and the objectives are usually just "collect something and get out of there alive". And while it can be pretty hard, it seems fair, specially since, if one character dies, you can use another character that starts right from the last floor entrance you went through, making progress lost minimal.

Still, after the first act, specially in the "origins" act, the game feels like it starts overstaying its welcome. Because of that, as well as the higher difficulty, while I still recommend playing the game, I suggest playing in short sessions so that you don't end up burning out.
