### 5/5 — Quality and actually free

*2021-05-04*

Good layout for the controls, lots of puzzles and actually completely free! No ads or in app purchases. It can be hard to find puzzle games that are just about the puzzles.

### 4/5 — 三角マスだけで済ませて

*2019-10-08, version 1.2*

三角マスを済ませた段階で実質的に解答終了。
最後に緑の四角マスを白くする作業は無駄なので省けるようにして欲しい。

### 5/5 — Very intuitive set up

*2017-12-15*

Really enjoy this app. I have been looking for a good Shaka Shaka app and have been disappointed with a lot of other ones. This one is set up very nicely with a good selection of puzzles. There are a few minor things that could be improved (English translation is off a little bit, an undo button would be nice, etc.) but overall I'm very satisfied.

### 2/5 — ゲーム性自体は悪くないが

*2016-11-10, version 1.1*

複数回答がある設問では、作成者の求めていた答え以外ではクリアできないのはゲームとして致命的かと思います。
