playing time decreased from 30 minutes to 15 minutes. that means. do you expect only 5 minutes a day because if you play you at 1x speed takes at least 10 minutes 5 minutes left to finish.
then. you even selling below the price about 10% ~ 20% you still profit by calculating the time most items.
then sell the same to be low. and time to suggest an item. suggest that the item has more value in your store so you can make more money selling it.
a positive if you liked!
