Spirit Run is an open clone of Temple Run where players have to try to escape an apocalyptic creature while avoiding obstacles ranging from very steep ledges to bear traps and rivers of lava.
Gameplay is identical to that of Temple Run: players control the position of their character by using the phone's accelerometer. You can turn corners by sliding your finger from left to right, and jump or slide on the ground by moving your finger up and down.
The only substantial difference between Spirit Run and other endless runners is that your characters can turn into an animal when they get enough amulets. This makes you invincible and lets you go faster for a few seconds. Depending on your character you can turn into a wolf, panda, fox, panther...
Spirit Run is quite a good endless runner with noteworthy graphics and perfect controls. Its only weakness is that it's just too similar to classics like Temple Run.
