I only lost because they started to take up 95% of the board
lol! You
must take a screenshot the next time you get to level 21!
I just position the player in a corner and move the curser out of the game's detectable area. Then, when the herd is just about to collide with the player I move the mouse back into the detectable area but in the opposite corner. Simple yet effective.
(well, judging by my score, not
too effective
)
