Lovely! Sorry that we didn't explain the chat further. It's really simple, actually! Randomly, a chatter can be replaced with a gifter, who gives you Cash (used in the shop), gives you double the gift amount, and removes the Time based on the gift amount!
The blue guy is actually one of our previous models AND our first enemy in the game. We didn't think that he would be such a menace even to us! haha.
We hope you score high!
