You can't make the time go faster in real world, do you?
Tamas' clocks run in same with the real world clocks, so Tamas grow adult when they are old enough.
Kokuma is right. A very nice way of saying it!
I also wish for Tamagotchis to change faster at times. But then again, sometimes I want the teenager stage to stay longer. You'll just have to wait.
But I must say one thing: Pausing it will make it take longer. If you change the battery, it also makes it longer, but it doesnt' impact it as much as pausing.
