### 5/5 — チーターの対処をして欲しい

*2025-11-16*

ゲームの内容自体はとても素晴らしいです！いつも楽しくプレイさせてもらっています！

ただ、チーターがいるので対処をお願いします。3ケタマッチにも4けたマッチにも出没しますが、4けたマッチに多く出没しているようです。名前はたまに変わっているようですが、今はyu7( ˘ ³˘)♡みたいな感じです。報告システムもない（あるかもしれませんが見つけれない）ので、ユーザーはどうしようもなく、マッチした時点で抜けると途中落ちとしてレートが下がるし、勝つ方法もないのでただただユーザーのレートが下がるだけです。ランキングは常に1位のようです。対処よろしくお願いします。

### 1/5 — 友達とやる分には、

*2025-08-19, version 3.1.0*

オンラインのレートがあまり意味ない。同レート帯の人と当たりにくい。あと、オンラインだと運が絡みます。実力もありますが9割overは運がらみです。友達とやりましょう。相手の誕生日とか、ユニフォーム番号などなど関係のあるところから数字を探していったり顔や仕草を見たりなど色々と試されて面白いです

### 1/5 — ゲームは面白いけど

*2025-07-30*

ゲームは面白いけど、それ以外のアイコンや自分のプロフィールを装飾するためのアイテムはコインが必要で、コインを手に入れるためには高校を見る必要があります。
その広告は3回に1回は見たことを無効にされてしまいイライラします。
ゲーム性が面白いだけに残念で、時間が経っても一向に改善されません。

### 1/5 — チーターがいる

*2025-07-29, version 3.1.0*

初めてやった時、番号を入れて始まった瞬間当てられました。
一回ならまだしも3回連続でされたのでチートを確信しました。

### 5/5 — こんなに楽しいゲームがあるのか

### 5/5 — 追加して欲しい機能

*2025-06-19*

とても楽しく遊ばせてもらっています！頭を使う良いゲームで、友達と一緒にプレイするのも盛り上がります。

さらに良くなると思う点として、「フレンドになる機能」や「チャットできる機能」があるともっと楽しくなると思います。気に入った相手と何度も対戦できたり、ちょっとした会話ができたりすると、より交流が深まって嬉しいです。

今後のアップデートに期待しています。開発応援しています！
