FAMITSU: I have a feeling that users are eagerly awaiting a so-called "photo mode" in the update that will allow them to take pictures freely.

Kim: Unfortunately, we can't give it to you right away, but we would like to implement it. If we do implement it, we want to make sure it is of high quality, and we are in the process of making it, so please be patient.

famitsu: Do you mean that you want to implement a function that goes beyond simply stopping time and taking pictures?

Kim: We are looking at a variety of features, so please bear with us.
