### 5/5 — 初めてのレビュー

*2026-09-10, version 1.7.13*

このゲームは五年程前にYouTubeで流行していたのを思い出し試しにプレイしてみるかと軽い気持ちでこのゲームをインストールしました。僕は数々のゲームをプレイし、ゲームで泣くと言うことが滅多にありませんでした。しかしこのゲームは別でした、そうです有り得ないほど泣きました。泣き喚いてしまいました。そして僕はレビューを書いたことが人生で一度もありませんでした。ネット通販も他のゲームも飲食店も何もかもです。しかし！このゲームはレビューしないと気が済みません！他にも神ゲーと言われるものをプレイしてきましたがこれは別格です。五年前に流行していたと言いましたが、まだまだ永遠に流行できる程の内容が詰まっています。最高のゲームをありがとう。

### 4/5 — バグを発見･･･

*2026-09-06, version 1.7.13*

ロボットを作るミニゲームで、完成しても何故か出品出来なくて、何回押しても出品出来なくて評価がEに。
そして普通の画面に戻っても何故か完成したロボットが表示されていた。
ゲーム自体はとても良いので、このバグを早く直して欲しいですq

### 4/5 — This game is amazing. I want to know more about this parasite. I’m obsessed with it.

*2026-08-23, version 1.7.13*

Oh my gosh, I love your game so much. I am obsessed. I can’t stop playing. I want you to make it where everyone can get a new ending. In the game, Parasite Days and the ending is you become a parasite and the parasite becomes your host and you will know what it’s like to be the parasite and talk to the watch and make it where there’s 10 new endings in Parasite Days but you’re a parasite so that will make 20 or 21 endings please!!!!!! Add this Literally so much people would love this, especially me!!!!!!!🤩🤩🥳🥳🥳🥳🤩🤩🤩🥳🥺🥺🥺

### 5/5 — I ABSOLUTELY LOVE IT

*2026-08-15, version 1.7.13*

I don't know much about english, so i'll write it in spanish.

Yo diría que es de los mejores juegos de Appstore con pixel art. No te obliga a comerte anuncios innecesarios, te va dando pistas si es que las ocupas (no te tira al vacío en cuanto a como continuar) y... bueno, no se. Es que simplemente es fantástico. 

Usualmente juego RPGs y novelas visuales en la compu, tipo Saya no Uta o Mad father. Me dio gusto encontrar un juego que, si bien puede no ser tan parecido a los anteriores, tiene un mundo simple, aunque trabajado, bastante interesante e inversivo. Me hubiese gustado saber más de la historia, alguna continuación o algo por el estilo... (solo llevo un final y no he visto los otros juegos más que solo el título JAJAJ, pero si los voy a probar. Espero encontrar más cosas que complementen el mundo ficticio).
