Ghosts have spawned

[TeliHub]

The ghosts spawn in the middle of the grid and they try to catch Pacman.

If they touch Pacman he's dead except if Pacman ate a big food during the 10 previous seconds.

The first and the second ghost start to move at time + 0s after the game starts.
The third one starts walking at time+ 3 seconds
The last one starts walking at time+ 6 seconds
