I must preface this with the fact that I don't have diagnosed OCD, but can empathise alot with the experience of having intrusive thoughts and compulsions due to my otherwise mental state at times as well as my Dermatillomania(which some argue is a form of OCD but I digress). That being said, in my humble eyes, I think the representation in this game is amazing, and the gameplay loop/elements perfectly capture the frustration and anxiety. A more subtle(?) thing I loved was the way that the FOV constricts the higher the anxiety, not only mimicking the tunnel vision given by repetitive thoughts and compulsions that you don't feel you have control over but also giving the player an unpleasant sensation that gradually worsens the longer a compulsion is delayed(again, mimicks the lived experience using its format as a game). It's all in all really clever and a GREAT tool imo to introduce people to/get people more familiar with what it's like to have OCD.
