Caffeine

Caffeine is the central theme of the game, as it is what the player must collect to maintain their run. While it is essential, it also has the drawback of making you increasingly faster, which makes the game far more difficult.

There are three different sources of caffeine in the game, each with varying levels of energy given.

Mug
Mugs are one of the three types of coffee, and the type shown in the title art. When a mug of coffee is collected, it will give +1 Caffeine.

Cup
Cups of coffee are another of the three types of coffee. It appears to be in a styrofoam cup, and will yield +2 Caffeine.

Can
Cans are the third and final type of coffee, though it is debatable if it truly is coffee. It is in a metallic can, and give +3 Caffeine upon collection. Due to their vibrant coloration and unique ding when collected, it can be theorized that it is not coffee, but an energy drink. However, they can be drank to begin the game.

Additionally, there seems to be a rare instance where the "Caffeine" modifier in the top right temporarily changes to "Disrespectful". The cause of this is not yet known.
