Well it's some little hard... The sheep have blue line and orange line, if you press on it with hand, you increase blue line and decrease orange, if press with cutter, it decrease blue line but increace orange. Orange line is line of sheep grow level, blue line is sheep wool level. If you try to cut wool from sheep with out wool, seep will damage you.
As close sheep to youre house, then more damage it will cause.
I guess it make this game some little playable for you!
