DEVS are trash. ### 1/5 — Honestly wouldn’t play any of their games. Shady developers *2023-10-31, version 7.39.12* Mailbox broken for several days. Developers refuse to answer or provide any feedback after multiple months with no new content. ### 1/5 — 運営の対応がゴミ *2023-05-30* 強い覚醒キャラを動画まで出して課金させといて、強い理由がバグだったから素材だけ戻します(返金はしません！)は詐欺すぎると思います。 無課金でゆるく遊ぶならいいと思いますが、課金はしない方がいいです。 (何故かこのレビューに不快なニックネームへの対応うんぬんという謎の運営からのリプがついてますが、これを見ていただければサポートのレベルもお察しですよね？ ユーザーの不満が全く伝わらないゴミ運営です…) アンインストールしました。 **Developer response:** 忍者大戦をプレイしていただき、ありがとうございます！貴重なお時間を割いてレビューを残して頂き、誠にありがとうございます。 ユーザーの皆様に不快感を与えるようなニックネームに対して素早く対処できなかった点、深くお詫び申し上げます。確認する次第、当該ニックネームは変更措置を行っており、今後同じことが再発しないよう、ニックネームの強制変更措置に関する事項を明記して告知致しました。頂上決戦コンテンツではニックネームの変更がリアルタイムで反映されないため、ニックネーム変更以降もゲーム内での反映が遅くなってしまいました。誠に申し訳ございません。至らない運営で失望を与えてしまい、心からお詫び申し上げます。忍者大戦は様々な国家の多様な価値観を持つユーザーたちが国境の隔たりなく楽しめるコンテンツを目指しております。今後とも、健全なゲーム環境を作り上げるため最善を尽くして参ります。 今後とも皆さまに快適にお楽しみいただけるように、運営チーム一同、より良いゲーム作りに尽力してまいります。 プレイ中、何か少しでもお気づきになったことなどございましたら、当レビュー欄や公式メールアドレスにてお聞かせくださいませ。 ■公式Twitter：https://twitter.com/ninjabattle_jp ■お問い合わせ先：ninja@gameduo.net ### 4/5 — Some bugs *2023-05-17, version 7.37.01* The gameplay is enjoyable and it’s simple, perfect for a mobile game and I would’ve given it 5 stars, however, there are a lot of loading and crashing issues, a few missions I try and play never load my rewards after I completed the mission, along with some random crashes when I open a different part of the menu, please fix asap ### 2/5 — Don’t get far *2023-02-28, version 7.33.04* I really want the devs to see this… I’m 150 mill right now, and I love the game. However, I can’t progress because the game can’t handle the amount of enemies on screen!!!… it craps out at a certain point. I WAS top 200, but I can’t keep up because the game freezes when there’s too many enemies and then I lose. Please fix ### 1/5 — Lost my progress *2023-02-18, version 7.32.00* I’ve been playing for hours and genuinely enjoying the game. But then some weird thing happened and lost all my in game purchase and game progress. Turned off so I am deleting this app. ### 5/5 — Crash *2023-02-09* Podia parar de crash, toda hora tem q fica reabrindo o jogo porque trava em load infinito ## Most critical reviews (10 lowest-rated) ### 1/5 — 何で運営が機能してないのに *2025-12-24* 配信継続してるの？ 運営する気無いならサ終すれば？ 運営が放置してる タダの集金アプリって認識 ### 1/5 — Lost all progress *2025-07-22, version 7.39.12* Played this game a ton. Obsessively I’ll admit. However, the update happened and I lost everything. Money spent wasted turned me off! ### 1/5 — Scam *2025-04-05, version 7.39.12* Randomly lost all data and progress on the game, spent some money on this game and now I’m trying to get it back. ### 1/5 — アップデートもなく不具合放置 *2025-01-19* 新規の方が搾取されるのは見ていられません。早くサービス終了して下さい。お願いします。 ### 1/5 — This game is a zombie *2024-09-03, version 7.39.12* I played this game a while back and it was just shy of an absolute 5 stars if it made a little more sense. Currently the devs have apparently jumped ship - game doesn't get updated or anything at all and there aren't any events anymore. Even the discord server for the game is completely dead and inactive. If you want to give this game a shot you're welcome to, but keep in mind that the game is no longer truly prime when there were events and tons of resources given out all the time. Good luck. ### 1/5 — Unplayable *2024-06-26* Even the tutorial is bugged and doesn’t work 👎🏻 ### 1/5 — 運営の放置が酷い *2024-06-26* ここまで酷い運営は無いね。 ### 1/5 — 微妙笑 *2024-06-19* これはすぐ飽きる笑 ### 1/5 — まじか... *2024-06-05* このゲームは急にアカウントが消えます。 ### 1/5 — 진짜 진지하게 *2024-03-30* 옛날에 잠깐 했던 게임 생각나서 다시 깔아서 하고 있는게 어느덧 반년이 훌쩍 넘어서 1년이 다되어갑니다 그런데 3달 전부터 업데이트 하나 없이 개발자는 가끔씩 카페에 왔다가 다시 가고를 반복하고 있습니다 지금 이 게임 하고 있는 사람들은 마을원들간의 정도 있지만 혹시나 개발자가 다시 돌아와서 열심히 하지 않을까 하는 기대심으로 하는 것도 있습니다 무조건 새로운 것과 참신한 걸 원하는게 아니라 이전에 했던 이벤트를 다시 해도 괜찮고 조금씩 조금씩 업데이트 해주시면 정말 재밌게 할 수 있을 것 같습니다 이 글이 묻힐 수도 있겠지만 한 번 이라도 보시고 생각이라도 해주시면 감사드리겠습니다 긴 글 읽어주셔서 감사합니다 ## Most praised reviews (10 highest-rated) ### 5/5 — 帰ってきて *2026-02-24* 運営戻ってきてくればかやろう、おれの青春返してくれーーんんんん ### 5/5 — Ninja fun! *2025-12-05, version 7.39.12* Great game to pass the time! ### 5/5 — 재밋어요 *2025-10-04* 진짜 재밌는 게임입니다 이 회사 게임중에 제일 재밌는 게임같은데 업데이트와 신규 유저 유입이 없어서 아쉽네요 다른게임 신경쓸시간 좀만 투자하셔서 갓겜 하나 살리셨으면 좋겠습니다 그리고 패키지는 솔직히 너무 비싼거 같습니다 가볍게 시작하는 유저가 사기에는 부담스러운 가격입니다.. 피드백 들어주시면 감사하겠습니다! ### 5/5 — 愛華ってキャラ好きだった *2025-03-29* もう更新されてないっぽいけど、とにかく愛華ってキャラが好きだった。PvPは全くしないから宝の持ち腐れだったけどとにかく愛華が好きでストーリーでもデイリーのやつでも愛華をずっと使ってた。愛華使う為に土属性の技入れてたなぁ。懐かしい。 ### 5/5 — Really good but I suggest one thing *2025-03-23, version 7.39.12* This game is really fun because of its abilities you use in the game but the thing about is that it has a time limit for each battle I recommend removing that since it is very annoying for me and others ### 5/5 — 배 17을 하고있는 유저입니다 *2024-08-15* 제목 그대로 배-17을 하고있는데 갑자기 전투력이 낮아졌습니다. 버그인가요? 빠른 답변 부탁드리겠습니다… 그리고 더 말할게 있는데요. 전투력이 6만은 거뜬히 넘었는데 갑자기 잠깐 사이에 1만6천으로 떨어졌습니다ㅠㅠ 빨리 답변 부탁드릴께요ㅠㅠ 간절합니다 ### 5/5 — 初めて約1ヶ月 *2024-07-15* このゲームは面白い！ ここ最近のゲームで1番ハマってます！ 面白いのは戦闘力が数値で分かるので自分がどれぐらい強くなったのかが実感しやすいところです！始めたては1000とかなんですが今自分は1500万まで来れました！でも上位のプレイヤーは100億とかの人もいるのでまだまだ強くなれることが楽しみです！忍術や忍法を駆使してステージをクリアした時の達成感がたまりません！ ガチャ要素もあって装備のために周回したりして運要素もあって丁度いいバランスだと思います！ 基本は一人プレイで里システムがあるので他のプレイヤーとも交流できます！ 運営さん素敵なゲームを作って頂きありがとうございます！これからも頑張ってください！ ### 5/5 — Make sure that one of the creators is reading *2024-07-07, version 7.39.12* There is one thing that I think you need to fix this game is a very fun and entertaining popular game but the one thing that is really bugging me is that as soon as I try to get to the game, it just is a black screen for like 20 or 15 minutes THATS all ### 5/5 — 왜 초기화 된거죠 *2023-05-29* 원래 하다가 오랜만에 업데이트 하고 들어오니까 기존에 있던것들이 몽땅 사라졌네요;;당황스럽습니다 제밋게 했던기억에 다시 할려핬는데 다 사라지니까 할 마음이 없어지네요 안타깝습니다. 그래도 게임은 아주아주 재밋었어요 다른 분들은 재밋게 즐겨 주셨으면 좋겠네요 그래도 재밋게 했던기억이 있었으미 감사했습니다 ### 5/5 — Game review *2023-02-15, version 7.32.00* I found the game quite interesting and would give it 5 stars. However, a bug seem to appeared sometime when you doing random thing and just stuck at the loading screen. I hope u guys will fix it soon. Overall, the game is great itself. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
