One of the monthly missions is 10,000 minutes. That's over 5.5 hours a day. This is pretty unreasonable and would require idling overnight or spending way too much time playing this game (

And, yes, I'm aware that the 10k number is even more absurd this month because we only have a week left but I'm going to let that slide. (less)
