Cute little game with easy to understand mechanics!
The strategy got a bit repetitive, but I think adding simple things like various levels with difficulty multipliers would work brilliantly! Add some fences, maybe something else that would occasionally spook the sheep so they might be less afraid of you and escape? Just thoughts, I think its quite original though! <3 Very cute! <3
Also, I got a score of 54 and would have gotten 60 were it not for one sneaky sheepy!
