When we feature a game on social media or YouTube, we may credit the creator's display name.

10. Changes to these terms
We may change these terms when needed. Before a change takes effect, we will announce the updated terms and the date they take effect on the service. If you keep using the service after that date, you agree to the updated terms.
11. Governing law and language
These terms are governed by the laws of Japan. Any dispute relating to the service will be subject to the exclusive jurisdiction of the district court that has jurisdiction over the operator's location as the court of first instance. The Japanese version of these terms is the official version, and it takes precedence over this English version.
