### 5/5 — 綺麗なゲーム

*2026-05-21*

ゲームが開けなくなったり、難問で先に進めなくなって離れたりしていて久々に開きました。やっとコンプリート。足掛け16年…
とても見た目が綺麗で頭を使うゲームです。三原色の絵の具を混ぜたことがあればわかります。じっくりがお好きな方におすすめ。

### 2/5 — 5 stars on iPad, 2 stars on iPhone

*2024-08-21, version 3.0*

This is a 5-star game, but the music never plays for me on the iPhone. It works great on the iPad.

### 5/5 — Clever and Original

*2022-09-18*

This game is very easy to understand, but very difficult to solve. They introduce new mechanics often, and let you skip levels. The game gets extremely difficult, if that is something you enjoy.

### 5/5 — Si tu aimes les puzzles games

*2020-12-09*

Très bien fait 
Aucune pub
Rejouabilité

### 1/5 — To reiterate another reviewer... not that great.

*2020-11-10*

Got this when it was free.
Played for a few minutes and deleted.
Neither interesting, challenging or fun.
Just a bit boring with annoying limitations.
Sorry this is negative but really don’t waste any money.

### 1/5 — 2面で詰む

*2020-03-27*

白玉と水色玉が出て、白を水色に重ねると右上に矢印が出現して『すへて混ぜ合わせるように』と出てくる。チュートリアルじゃないのかこれ？

### 5/5 — Русский язык

Kotoro is back!

We have remade the entire game on a completely new game engine and we hope you enjoy it.

What happened?
The original game engine we used to develop Kotoro was no longer being supported so we were unable to update the game to meet the 64-bit requirement for the newer iOS versions. As a result, we have remade Kotoro from scratch on a new game engine. If you've bought the game before, you can download the game again for free with the same Apple ID you initially used to buy Kotoro.

What's next?
We are thinking about adding a new chapter to the game further down the road. Meanwhile, if you'd like to support us please consider purchasing our other games on the App Store.
