Sadly, there is no sprint, and your character cares more about enjoying his soda than going anywhere in a hurry.

BUT... there is a way to go noticeably faster. Strafing. Don't worry, it's not nearly as hard as bunny hopping or momentum in Quake.

All you have to do is use A or D ONLY(sideways movement) to move instead of using W, and you'll be flying. Of course, it's no sprint. but it's still a lot faster than just the standard forward walk.

To conclude, press only A or only D when you're walking. You'll become a supersonic crab, grabbing bonus sodas sideways at blinding speeds.
