Finally finished the game myself. I'd say the game is pretty good and describe the story as attractive in the sense when playing through the game, I kept wanting to see the next part of it. I like the ingenious language trick a lot.
However, after finishing the game and seeing the whole story, I just feel a couple of early events (while serving as misdirection) don't fit well with the overall story. Not bad enough to be outright logical contradictions, but feels unreasonable nonetheless when looking back. The mid-game story also set me up to expect more fireworks than there is at the end of the story. This may be the fault of my own expectation though.
Besides, my doubt about how speakers talk over the radio like they know exactly where I am and what I'm looking at remains. Potential access to the visible security cameras certainly won't cut it. Some of the content and exquisite timing of their lines make me even hesitate to say an assumption of hidden security cameras can make it right. The only way I can accept this aspect is to see it as a gimmicky game guidance system and not to see it in the context of the story.
In terms of gameplay, what I like most is I can save all game status at any point. Together with the vita chamber revival system, the game is made easy, which suits me well.
Even though I was only playing on medium, when things go right for me, I save game. Every time I suspect things may not go well for me soon, I save game. On average, I probably save 5-10 times/hour. I probably save game more often than I use plasmids.
