I'm going to tell you some stuff about Pictochat:
Change languge: Look at the bottom-left part of the screen it should show some icons, click on one and it will change the language ( there's even a Pictochat one just for fun :)

Repeting stuff you wrote down: Below where it says " SEND " there's a button pointing down at something, click on it at the answer that you just wroten down will come on the bottom screen, its also used to change it a little

Looking at your other answers: At the top-left screen are arows, there used to go up and down to view other stuff you wrote down

Play by forself!: Last, you don't have to play with a friend, you can play with youself too!
