### 4/5 — Good story and nice calming music

*2025-08-13, version 1.5*

The graphics are so good and detailed everything feels like a good animation from Japan or a great cartoon, nothing looks out of place. Except the robots in the 3rd world. The lighting is also really nice and the environment of the world feels so alive and beautiful. All the characters fit right in this world and specially animals characters the robots in the 3rd world look a bit out of place but they do look cool. The music is really relaxing and very calming. The story was both beautiful and sad but with a happy ending to the girl story with the bird. I needed a walkthrough for the 3rd and a of 4th world’s but the puzzles were both challenging and tricky but well done. 4.5 / 5 Stars.

### 1/5 — The hints don’t work

*2025-08-08, version 1.5*

The hints don’t work.

### 1/5 — 進まない

*2023-08-31, version 1.5*

一話から鳥の矢が取れない

### 5/5 — お願いです。

*2023-05-14, version 1.5*

こちらにも同じようなレビューを書いて申し訳ないのですが、
間違いなく良作であるスラプリが現在のiPhoneのバージョンでは遊べなくなっています。
是非にまた遊べるようにしていただきたいです。
どうかあの古き良き作品が復活しますように。

### 3/5 — This game is my childhood

*2023-05-01, version 1.5*

From the story to the art. It’s beautiful. The puzzles may be a little hard after the second chapter, but they reward with the story.

This game was a major part of my life in 2020

### 1/5 — 進行不能バグ……

*2023-02-27, version 1.5*

鳥にお魚が渡せません

### 3/5 — 謎解きは面白いけど途中で断念…

*2022-11-04, version 1.5*

謎解きは面白いです。ヒントが少なく自力感で突破していく感じも私は好きです。
ただ途中で、子守してる親鳥さんの卵を…のシーンで心が萎え継続無理でした。
ゲームとはいえ鬼畜すぎる。美しい自然界の世界観がぶち壊し。鳥好きにはしんどかった。

### 1/5 — こじつけ多いな

*2022-09-17, version 1.5*

エフェクトが小さくて見づらい
窓で比べさせるなら大きくて分かりやすく
イラストが辛くて見ずらい
ひだりから、うえから、順番にするならその根拠がない

### 5/5 — 好きです

*2022-08-17, version 1.5*

他にこのクオリティでこんな雰囲気の作品はない
新しい作品がみたい

### 3/5 — 2までやってみて

*2022-07-23, version 1.5*

普段食べてる分には何も思わないけど、卵を取られた鳥さんが可哀想で心苦しかったです。
会話の中のアイテムをタップするのが分からず苦戦しました。
