### 5/5 — Jules

*2026-05-20*

Okay this app is soo comforting for me. Ive been playing this app since 2018. I love looking at the jellies and like watching them swim so much to calm me down. I hope the developer of this app will update it soon . I want the developer to like make you add like 20+ more of ur favorite jellies soon. Like my favorite is the Japanese Sea Nettle Jellyfish! But yeah Imma manifest that the developer of this app will update that. And also will update some more colors as well! So that way when u press ur two fingers u can see some new colors! But yeah that’s all I have to say about this app. It’s a 10/10 for me. 🤍🤍🤍

issue is that if you have screen saver on Apple TV, the screen saver will override the app. IT SHOULD NOT HAPPEN. They should fix this. I paid for it.

改めて再課金必要でしょうか？
