If there would be 1/2 star possible, you have earned it.Takes a long time to earn stars, & when every action costs 2 or 3 stars, progress is slow. Another update, progress very slow if you do not spend...keeps wanting to update despite doing it almost every day, its getting harder to ever get a star..it updates every time I visit now, takes the fun away. Too bad, it could be a fun game, its different.
