Ok, I will be honest with you. You had me destroyed. I had been going for 1.5 year to the therapist, struggling with anxiety, minor depression symptoms and some other stuff. This is perfect depiction of a struggle to be perfect. The difficulty is very high and one mistake can cost you a lot of time. I love it. It's PERFECT. I don't want too say too much to do not spoil the experience for people reading the comments before they try the game.
In summary: it's great and it's needed. This should be used to show people how it feels to have anxiety. Really, really great job!
