### 2/5 — 判定エラー

*2025-09-21, version 1.1*

隣接が同じ色になってる状態でクリア判定になる

### 1/5 — wanna spend money?

*2023-11-23, version 1.1*

i sure hope you do because after doing a few you gotta "purchase the addon"... no thanks you lil ea wannabe

### 1/5 — Why?

*2023-03-25, version 1.1*

Why does it say I have to pay one dollar just so I can do 3 more?

### 4/5 — 音量やばい

*2022-09-30, version 1.1*

音が大きすぎる。音量をゼロにしても聞こえる。何かしらの方法で消せるなら、方法を分かり易いところに付け加えて欲しい

### 3/5 — I can’t get my things in the gallery

*2022-05-23, version 1.1*

Good game but I need something to put my pictures in the gallery.
It’s really confusing.

### 3/5 — 日中米だけだと...

*2022-01-01, version 1.1*

独仏伊韓カナダフィンランド豪も追加して欲しいですね。
追加して欲しいなぁ(p_-)チラッ

ふざけました マジで追加してください

### 1/5 — Too boring

*2021-03-06, version 1.1*

This game is to boring and is not really creative, could you make this more enjoyable and more creative?

### 4/5 — Love apps based on 4 color logic.

*2021-01-11, version 1.1*

So happy to see your app even with flaws and obvious lack of interest by developers after creating it. There was a very good version on android. Platform several years ago and I miss it after sifting back to iOS. Would encourage developers to further enhance game.

### 3/5 — 音を消して欲しい

*2020-06-23, version 1.1*

マナーモードにしないと音が消えないシステムをやめて欲しい。通知音じゃないほうのボリュームを下げたら消えるようにして。
内容自体は楽しくて好きです。
普通に隣合った色があるのにクリアになったりと少しガバガバな所はありますが。

### 5/5 — ヘウレーカ

*2019-10-11, version 1.1*

ヘウレーカから来ました。コツが、法則が、あるようなないような。楽しいです。
ただ、第９問？の真ん中左寄りの虹が、輪郭線が繋がってなくて完了てわきません。そこから進めなくて悲しいです(*_*)
