Here is an advice from a Japanese person. When the title screen is displayed in Japanese, "Badges" is displayed as "きしょう", but "きしょう" is hard to understand, so it should be displayed as "バッジ".
When I made this game 2 years ago I translated most of the Japanese texts using my limited knowledge and GoogleTL. I'll keep in mind this word if I update the game in the future.
