You need game money to get something new in My Talking Tom. You can earn it while playing, or you can buy it. There is an upgrade system that you can upgrade by spending time with your cat and ensuring that his needs are met. When you upgrade, you will unlock new items and items from the store.
The graphics and overall presentation in the game have not changed much. Cats still look the same to a large extent, and Tom seems to be the only character in the game, with no sign of Angela who can talk to his girlfriend or dog Ben who can talk to his hated neighbor.
