This is a special idea
I like the insanity and stupidity in the game.
It requires some touching up before it is finished.
If you want the cows to reappear if you enter the game again just erase the event instead of turning on local switches.
If you want their positions to be random you should arrange them at startup
I think you should add the ability to stop the game if all cows are caught.
You should allow the player to specify the number of cows in 2 digits
Well... You can make max whatever you feel like.
A couple of things to think about
P.s. I meant it as a joke when I said you should make a cow hunting game
