Over on the Tactics Ogre: Let Us Cling Together twitter account, a member of the staff mentioned how the Japanese version allows players to input hiragana, katakana, kanji, alphabet, and symbols. As example, they named their team an emoticon.
Oh, team hugging face, that’s your name?
Also on Twitter, it was mentioned Tactics Ogre: Let Us Cling Together has a 1350KB save file.
