Ingenious game design starting on the puzzles themselves up to the whole structure of the game and progression. As someone who managed to come in blind to one of the most well-known of game series of the last 2 decades I was quite surprised by the second half of the game. I'm a sucker for the sterile shady corporation setting. Can't really go wrong with it and a few jokes here and there rly help to take the edge off it, laughed a few times. Very cool and concise game to beat in one sitting. Looking forward for Portal 2
