phew took me ages to get the max score on this version! It's getting hard!
Last night I was playing in my bed on my iPad, and I was getting that dog to appear in the corners several times. I didn't understand what the dog did, couldn't observe any effect. Finished the game eventually, but did not get max score clear.
Today I played on my desktop PC, and improved my play to do several max clears, but I never saw the dog. I wonder what happened to it and where it lurked throughout my play :(
What does the dog do?
