At first I felt the monsters were too gimmicky and playing their games would take time away from my lens making. I tried a few quests and felt they were worthwhile in giving me rewards. I was able to give a lens boost to two lenses that were lurking just below the first tier. If the boost lasts for the whole month, that translates into an extra $15 each in income.
Then I was able to pass along 2 purple stars to worthy lenses and one lensmaster gave me a purple star. Suddenly, I’m liking the monsters more and more.
