Just started!

Well, I have some questions about the tamagotchi

There's a sort of bar or sumthing in the status screen. wtf is that?

and about those hidden parameters. Like Heart Needs and Body Needs. Wasn't there a way to like press some butons in status mode and you can see those hidden parameters?

Ok well theat "bar" is called the disipline meter, if your tama beebs at you and dosen't need praise or comforting he just is playing you need to disipline him this way he won't grow up into a lazy charecter, also you can not see the "Hidden Pirimeters" because there hidden, but you can see the Age, (1 day is one of there years) Amount of Happy Hearts, Food hearts, Disipline Level, Generation level, (such as if this is your third babie without reseting and you keep breeding) and the name which you get to coose every new baby you have.

another word is training bar
