The Audio is so on point, you can feel the breathing inside your mind. And it progressively getting more epic with each level passed is so satisfying. Headphones are really needed to fully appreciate it.
I also really liked the controls. It was a creative use of circles/loops to mark/find the distractions. The line representing attention is implemented very smoothly, despite the arbitrary shape from user's mouse movement it doesn't feel jagged and the way it slowly thins out to communicated how much length is left is done very cleanly.
The level of polish is unreal for a game jam.
