ADS

Love the game but there are WAY too many forced unskippable ads. Watching an ad for a boost i understand. I can play for 5 minutes without an ugly unskippable ad that I can only get out of by closing and reopening the game! It’s unplayable! I shouldn’t have to pay to get rid of the ads just to play the game!

Amazing!

Wonderful game! Super easy, relaxing, not overstimulating, free, and minimal ads. The fish are also very neat looking

Peace and sleep

I wish there were more patterns! But I still love the game, 🙂 it really is a zen game I always play it when I have a bad day or just to relax I love naming the koi and the music (so relaxing)but I can’t figure out how awake my dragons 🤔there is no awaken button on my screen

延々とやってしまう

最初は何をどうすればいいのか分からず、ヘルプで遊び方を確認するまでは手探りでした。
やり方がちゃんと分かってからは、ずっと遊んでられるヤバいやつと判明(褒め言葉)。
充電切れるまでやり続けられます、やり続けてしまいます。
真珠の鯉の卵の厳選や真珠の入手などは厳しい部分がありますが、そんなの些細な問題です。
時間が溶けるので、時間の使い方が下手な私はやむなくアンインストールしました。
時間の上手く使えるようになるか、他のゲームをクリアしたら、また入れるかもしれません。
残念な点としては…鯉や鯉の食べる虫は割とリアルなのに、龍はデフォルメされててなんだか不自然な可愛さだと感じました。
アプリの雰囲気としては、リアルデザインが良かったかなと。
