How to advance quickly in game

It's very easy to advance in game, it's a 3 letter word. Ads.

Ads are a very important thing to do in game because they give you a variety of boosts and they help the game. Some of the boosts are 2x Experience, 30 S-Bullets, Gain food and water, and you get to collect more loot on runs without having to pay S-Bullets. Take advantage of this guys, I'm in the top 100 in the world because of them and I haven't payed a dime yet. Hope it helps! :)
