### 2/5 — ずっと練習してたい

*2024-12-26, version 2.0.1*

ランキング無しでずっと練習出来る処を作って頂けたらとっても嬉しいです。
小学生の子と一緒に2Pので楽しく遊んだりもしてます、お母さんも大のお気に入りでね、好いアプリ。
コント無し、倒されても続きからエンドレスに出来たら最高。
唯ね、敵が強過ぎるのと、右下に出る数字が押すまでの経過時間か、合ってるのかも解らないε-(´∀｀; )説明をちゃんとしてくれたら、お年寄り〜小ちゃい子迄もっと楽しく遊べるだけど、其処も残念。
後、WiFi付けててもビデオの読み込み失敗したとか言われてコンティニュー出来ないのがかなり困ってます。

### 5/5 — Simple fun.

*2020-07-31*

A fun game for those with quick reflexes. But a quick warning: certain enemies are borderline impossible, the quickest I ever got was 23, and I found an enemy that can do it in 7. Don’t think anyone alive can beat that, but good luck if you try!

**Developer response:** It's quite a challenge, isn't it? Thanks for your feedback. We're glad you had fun. Keep slaying!

### 1/5 — 起動しない

*2020-03-04, version 1.0.1*

iOSです。起動しませーん泣

### 5/5 — 今のところ満足。

*2020-03-04, version 1.0.1*

ゲーム性はいいし楽しい。ただ、キャラ選択ができるともっと嬉しい。正直カメが欲しい。どこまで行けたかとかでコインとかが貰えるとかでそのコインでキャラが買えるとかそんな感じだとほんとにありがたい。まあゲーム性は十分満足してるから星5です。以上！
