Sleep

A good sleep is needed to regain your mood. Mood decreases by 1 each hour and affects your performance. As you increase the ticks, your gains in mood rise by 1 per tick. For example, in the first tick you gain 1 mood, in the second tick 2 mood etc. After 10 ticks you gain 55 mood in total. When you reach your max mood you wake up automatically. Interrupting your sleep is not a good idea as your mood will not increase.

- Some IQ based activities like 'operate' are not affected by mood.
