Square Enix might be working on a new Mana game? A trademark for*Rise of Mana filed by Square Enix Japan suggests that’s the case, but the game may not be a full blown Mana title. Rise of Mana could be a localized version of Circle of Mana, a social game released by GREE in Japan. A day earlier, Square Enix registered a trademark for Slimeshot which is most likely a localized version of an iOS game where you flick a slime to collect coins. Both games are available in Japan for iOS and Android devices.
