### 3/5 — 効果音さえ出してくれれば…

*2011-05-31*

全国各地の写真を使っていて、日本中の風景の中から選択して楽しむ事が最初から出来る。ヒントの出し方も、風景に対するコメントを兼ねたような文章で、作者のセンスを感じます。
なのに！なんで音が全く無いんだー！
正解/不正解の効果音ぐらい入れようよ！
まぁ、アハ体験だけのアプリで五つ星付ける方はなかなか居ないかも知れませんが、音さえ入れば、国内ではかなり高評価を得られるアプリだと思います。
今は無いので、★2つ減点です。
あとは、アイコンがダサいね（；^ω^）

### 5/5 — とっても大好き♡〜ノ(=･`▽´･=)ノ〜♡

お～‼同じ問題が出て、同じところが変化するのかと思うと…気まぐれだけど、何回目かには違う。
多分…少しバグ有りかな？
リプレイ押すと固まったり、次の問題出たりしますが、殆ど快適にあそべます。
続編出たら絶対買うぞお☆〜（ゝ。∂）

### 4/5 — この値段なら
