Moving pacman(picturebox) in an array, Visual C#

Trying to get pacman to move in grid, only can move through ones, stops when he hits a 0(the wall). Have four separate timers for directions that activate on keypress. Have only started with him moving right at the moment, for some reason he moves 4 spaces(int move = 4), then stops and will no longer move right.

public partial class Form1 : Form
    {
        int xg = 1, yg = 1;
        int move = 4;
        // 28 x 31 grid which functions as the map
        int[,] map = {{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0},                            {0,1,1,1,1,1,1,1,1,1,1,1,1,0,0,1,1,1,1,1,1,1,1,1,1,1,1,0},
