In the game, a coffee with angel wings would be flying around. If you tap it, you will look like you are on fire and your points (when you tap the screen) would be double for a few seconds. It is considered a power-up.
Types[]
There are two types of coffee. The blue one is a more common type. It doubles how much taps to complete a video. The other one is the red one with a yellow star in the middle, it appears that it is flying much faster than the blue one. It can be received by the Messenger by watching an ad. It triples every tap you do which is pretty effective. There is also a very rare chance of it flying by without you getting an ad.
