Looking back on it two years on... I also agree that Act 3 was the weakest of the game. I talk about it more in my retrospective, but by the time I was working on Act 3, I reached a "ceiling" with the game's story that I couldn't break through, so I wanted to just get it done. That's probably why it felt so rushed and disjointed compared to the rest of the game, haha. If I were working on Bad Faith now, I would've probably signaled Magda's heel turn more in Act 2. Maybe make her have smaller violent outbursts - something like that.
I'm glad you liked the first two acts though! I'm still quite proud of them and the tension they bring to the overall story.
