Feels like playing a game or watching an interactive, in which you need to make a choice against a clock. Just... in a more open-ended word. Or as writing homework when being totally sleep deprived, and any break means a risk of falling asleep (blurry graphics reinforce it a lot). Or writing an important email, when there is 2% of battery life.
