Gold coins are easy to collect by following their trails. When coins appear high against walls you can jump up against the flat part of the wall to wall run to reach them. You can also use that move to avoid enemies that are on the ground.
Crushers
This is a very large enemy armed with a giant hammer. He takes up two lanes, and getting hit with his hammer will end your run. When facing a Crusher, look at which lane he is holding his hammer in. That will be the lane that will get hit. Dodge his hammer then slide into him to knock him back. After he flies backwards down the path, he will try to hit you again. Dodge the hammer again, then slide into his exposed half to take him out.
Items
You must reach a checkpoint in order to save all the items that you ahve gathered. When you run out of lives, you will lose all the items gathered since your last checkpoint stash. Better quality items can be found the higher you are. You will also be able to enter different dungeons, which can be completed to be rewarded with treasure chests that contain rare items or premium currency.
Monster difficulty
During game play, numbers will appear over the heads of the monsters that you encounter. That number corresponds to how many times they must be hit in order to be eliminated. Monsters with numbers greater than 1 will be pushed back when hit.
Orbs
Collect the glowing blue orbs to purchase an extra life during a run. For each extra life bought, the orb cost to revive will increase. The first revive only costs one orb. Consider how close you are to a checkpoint before deciding to use an orb.
Runes
You can fine runes during every run. After five runes are collected, a portal will send you into space.
Scoring
Unlike similar games which award points based on distance traveled, you will score better based monsters destroyed. Eliminate as many as possible to score points.
Walls
While wall running, swipe up to jump up, then swipe horizontally while in the air. If done correctly, you will jump on top of the wall.
Wizards
Wizards will teleport away and summon other enemies to get in your way. Either avoid or eliminate their minions. Then catch up to the Wizard to take him out.
