Notes on Permissions required:
Zen Koi 2 is free to download and play. However, optional items are available via In-App Purchase within the game to expand upon your gameplay experience.
Zen Koi 2 gives away free pearls when you watch video ads. On some devices, those ads need to be stored temporarily on the external memory card. For that to work, please allow Zen Koi 2 permission to 'access photos, media and files'.
