Thanks for the kind words and feedback!
I think you hit the nail on the head at the end there - I’d have to be careful about adding too much difficulty, as a greater challenge could make the experience more tense, but it runs a risk of over-gamifying things; pushing it away from being a simulator.
That said, an anxiety attack shouldn't be a walk in the part so perhaps there was still room to increase the challenge slightly without losing the game’s identity... hmmm, something for me to think on. Thanks again!
