The major one is that, with that kind of movement sometimes the snake aint into the propper position to go into the pellets way you know, so i have to go back and forth to adjust it into the right position to so i can turn to the desire position. Im not sure if im explaining it propperly. So, is it possible for me to make the snake move exactly one block for each movement? Instead of a free movement to any desire position? That would solve the problem im having.

Thanks for the tutorial and i would appreciate if you could help me out.
