Thanks for playing and for the warm review!
Haha. Yeah, including the run mechanic made it too easy to run away XD. It was included to let the player get around more fast, as some players said to me that the walk speed made it take too long to get around the level.
I need to think of some mechanic to make sure the player don't abuse it. Maybe I will turn the zombies in Usain Bolt when the player run away from battle XD
