Some player said the card movement is too unreasonable, actually, I just want to made the movement simple and easy to control before, but seems not satisfy the players' feeling, so I made some changes today.
1. you can't turn around without move forward any more
2. No "reverse is backwards" problem any more, when you go forward, left is turning left, when you go backward, left is turing right.
3. some balance changed
4. add a Level UI, future I will make more uses about it.
5. fixed the NPC position is not touching the ground problem
6. add more tips.
