I don't know why quoting is often broken on my phone. Anyway, here's a quote from the devs:
“In terms of the standard difficulty, it does adjust based on player performance. I’d like to believe that you were doing really well and so the difficulty ramped up even more. But we have it tuned so that no matter how well you’re doing, there’s always going to be that sense of dread and tension there. Also, we are definitely implementing things that assist the player if they choose to utilize that stuff such as auto game. If a player thinks, ‘Here, I’d rather have an easier time going through this,’ we will have those sorts of options as well.”
