We've been working on adding Steam achievements to the game and we're almost ready to launch. We know this is something that the community has been asking for and we're looking forward to the new version. Please stay tuned over the coming days. 近日中に実績対応のアップデートが行われる予定です。 更新され次第NEWSでお知らせ致しますので、今しばらくお待ちください。 どうぞお楽しみに！
