Ok, Ill type almost every feature.
1- Mail, there is a mail icon, and it will flash when you get mail. Sometimes, a burglar will come, and sometimes the king will give your tama money! Its really exiting!
2- Jobs, a couple days after your tama turns an adult, he will get mail telling him he will get a job. Its pretty tricky, and Im trying to figure out how to know what you have.
Anyways, your tamagotchi can be a Model, scientist, ect.
3- Its easier to get points, which I love. But the prices go up pretty high!
