I particularly find this games forgiving gameplay, frantic action, and stretched out comedy very enjoyable. I do however see, as other probably notice, it feels a little empty in upgrades. Maybe if you could buy rare units that could appear in the game to give assistance - maybe some sort of spartan rush than runs ahead and knocks down everything in your way or a chance for rare sheep types like a ram to appear that knocks down runners in front of you while hurdles still stop it. A few themed upgrades for characters to appear on your run and help you would add a bit more depth and longevity.
fun and very funny game, I like it nonetheless.
