I really enjoyed this game (as much as you can enjoy playing a simulation of living with anxiety lol). There are some touches in it that I'm not sure are intentional or are just part of the game engine; looking around with the mouse can feel a bit dreamlike and I had trouble clicking on two of the objects I needed to complete my task because the cursor would constantly switch between the mouse pointer and the click finger, so it took a bit of frantic clicking to get it to work. If they're intentional they're great, if they're unintentional I say leave them in because they really add to the feeling of anxiety and trying to concentrate!
The part where you try to make the negative thoughts go away and some keep coming back anyway, or moving around, that was a nice touch.
The game gets its point across very well in a short period of time, a chunk of a person's day with no ending where they conquer it all - after all, this is only the beginning of Mary's journey. As a slice of life of someone who has anxiety it's a very good portrayal and I hope it can help others understand. Very good work :)
