New challenges every time you start
When starting a level, the game puts up a challenge to earn a little extra loot if you complete it.
Change lanes to survive
You'll need to swipe to change lanes in order to avoid obstacles.
Buy upgrades for your run
Head to the store between runs to upgrade the weapons and shields you pick up. You also can purchase temporary upgrades like potions to give you an extra chance on your next run.
Earn feats for more cash
Completing challenges earns you feats that often offer a pretty good payoff.
One epic fail!
If I had swiped left or right, I would have survived, but the middle lane made me slam into a door.
