This IFComp 2015 game centers on understanding and experiencing OCD. It has a nice visual feel, with a fixed-letter-spacing font and some purposely grainy photos/images.
You are diagnosed with OCD, and you learn that it's not what people think it is. You experience OCD as you struggle with how to spend your day and struggle with intrusive thoughts presented in an interesting way.
Overall, a mid-length game. You get a summary at the end describing how you're doing and what your future might be like.
If you are interested in OCD, definitely check this game out.
