Rough translation:
Our team often reference popular internet memes for placeholders in the prototype stage. We accidentally did not delete all of them in this version because of release sync. We do not have any intention to attack or insult. They have been removed in v1.0.5.
This controversy shows that our team is not careful enough in the due process. As a gaming company, we have a lot to improve. We apologize for all affected parties. Please forgive us.
All responsibilities are on us.
