### 5/5 — 必要十分な優良アプリ

*2026-10-19*

選曲画面もリズムゲーム画面も軽快かつスムーズな動作で優良アプリだと思います。
アプデないかなーと思っていたのですが、SEの個別音量調節ができるよう修正いただいたのがとても嬉しいです。

今のままでもかなり十分ですが、ほんっとうに厚かましく欲を言うなら、曲の検索、SUBTITLE(JA)の表示、TITLEJAの表示、.tjaファイル名以外による曲のソート(例えば、TITLEJA)、曲一覧で王冠表示、などが個人的な希望です。

うるさくてすみません、以下はちょっとだけ気になった仕様です。
装飾的に譜面分岐を利用しているタイプの(例えば、NやEがノーツ0個でMに強制分岐するような)譜面で、ノルマゲージが1コンボで満タン/1ミスで空になることがあります。
また、小節中のノーツがない部分で装飾的に短期間のGOGOSTARTとGOGOENDがある場合、ゲーム画面の表示が切り替わりません。
あと、これはあまりわかっていないのですが、LYRICSなど非対応のタグで小節中に改行が挟まると、カンマがなくても小節の区切りだと認識しているように思います。

### 3/5 — 広告がとにかく邪魔です

*2026-10-18*

スマホで太鼓できてとても嬉しいですが、とにかく広告が多すぎると感じます。どんな値段でもいいので、どうかお金を払わせて広告をなくすオプションをお願いします。

### 1/5 — 一坨

*2026-08-20*

就一首歌还不好玩而且很多键都打不上整体一坨

### 4/5 — 为什么要联网

*2026-08-12*

总体来说挺好的但是为什么本地游戏要联网呢，一联网就一大堆广告

### 4/5 — Happy that it’s free, but i have a problem

*2026-04-08*

Hey, I really like Taiko no Tatsujin, but sadly it costs money and the nearest taiko game around here is a long way in Arcade Club. So I’m happy a free version was made for mobile, but I have something to ask. Can you add songs, and a level editor? It might be too much to ask, but im hoping a bit more content could be added.

### 1/5 — Add more songs

*2026-03-15*

I ONLY HAVE 1 SONGS ADD MORE!

### 1/5 — 666就有一歌曲

*2026-03-07*

不是就有一个歌曲(剩下懒的说了)

### 4/5 — 広告は多い

*2026-03-02*

使う人はぜひ参考に。
①このアプリの良い点と改善してほしい(良くない)点 ②曲の入れ方 ③譜面の作り方 を残しておきます。



ーこのアプリの良い点ー

・曲を入れれば無料で何曲も遊べる
・スキンもダウンロードすれば自由に変えれる
・創作譜面を動かすことができる
・研究に使える
・判定をms単位で設定できる

ー良くない・改善してほしい点ー

・たまに音ズレする
　↑タスクキルすれば大体なおる
　　曲ごとにオフセットを変えてみる
・広告が結構入る
　↑機内モードにしたら減るが、
　　プレイできなくなることも
・自分で曲を入れないと一曲しか遊べない
　↑冷静に考えれば当たり前ではある

・「はじめからやりなおす」ボタンを追加
　↑本当に欲しい
・大音符のエフェクトの追加
・選曲画面で自分の記録を表示(良の数等)
・選曲画面で縦書きにする機能の追加

　基本的に神アプリですが、改善してほしい点がいくつかあったので星4になりました。


ー曲の入れ方ー
1、「(入れたい曲名)　太鼓さん次郎」で検索
2、アップローダーからzipをダウンロード
　　(全難易度譜面配布 などのサイト)
3、ファイルに入ったzipを共有→太鼓さん大次郎に送る
　(サイトから直接でもOK)
これで恐らくできます。


ー譜面の作り方ー
　私はiPhoneに元から入っていた「pages」を使っています。

1、pages で＋を押して書き始める
2、ヘッダや命令に関しては調べる
　( 1→ドン、2→カッ みたいな感じ)
3、作ったら(…)のような所を押して書き出し
　　標準テキストを選択する
4、このiPhone内→太鼓さん大次郎のファイルに入れる(このとき、曲ごとに分けると後々見やすくなる)
5、音源データ(m4a,ogg,mp3など)を同じファイル内に入れる
　音源のm4aについてはボイスメモやgaragebandなどのも使うことができます。
ショートカットアプリを使って、動画から取り出すことも可能です。

　これで問題がなければできるかと

(ネット上の音源やスキンをダウンロードする際は自己責任でお願いします)

### 4/5 — 載入更多歌曲

*2026-01-22, version 2.0.3*

非常棒，要是能夠去除廣告會比較好，沒有廣告給滿星～

### 4/5 — Tải được nhiều map mà không tải được skin

*2025-12-06, version 2.0.3*
