I have made a riddle game in english and I would like to offer you a multiple review exchange.
One for one, I can give you up to 6 real installs (uninstall not sooner than 4 days), reviews, stars and G+ from real people with real accounts. some are my family members, some are my friends and all are willing to participate.
getting your game to higher ranks is hard so lets help each other
