### 5/5 — So fun

*2025-10-30*

This game has a simple concept, but is very well executed. The levels are well thought out and grow more challenging, but not impossible. The graphics are nice, the controls are smooth, and it is a lot of fun. Proof that a game doesn’t need to have a bunch of useless flash to be entertaining.

### 5/5 — Качественная инди игра

*2023-08-07*

Игра приятная, не перегруженная, качественная, со своим шармом и шикарным звуковым сопровождением. Это алмаз затерявшийся в недрах корзины инди игр. Она так же есть в Стиме. Кстати, создал игру российский разработчик. Узнал об игре в Стиме, там дэмка была, я попробовал. Нужно и Эпсторе дэмки делать, иначе как поймёшь нравится ли игра.

### 5/5 — Top

*2022-03-04*

Konsequente Weiterentwicklung der vorangegangenen Spiele. Alle drei haben eine 5 Sterne Bewertung mehr als verdient.

### 5/5 — Great game but so hard

*2021-11-15*

Love all your games. Unit 404 is great but wow, super difficult. I’m about halfway through but not sure I will be able to finish.

### 5/5 — 抜群の難しさ

*2021-07-05*

これは凄い。動かせるのが少ないのに、なぜここまで歯ごたえがある難易度なのか不思議でたまらない。

言うなれば、バズルゲームの金字塔「倉庫番」の荷物が少ないのにメチャクチャ悩む面しか入っていない感じ。

 そこら辺の軟弱なバズルゲームに飽き飽きしている人にこそプレイして欲しい。

この作者の他のゲームも面白い。
セットで買っても損はないと思う

### 2/5 — 英語分かりません

*2021-05-01*

他のパズルゲームもかなり好評だったので購入しました。3つバンドルの奴です。残念ながら英語が分からず無事死亡しました。レビュー評価がめちゃくちゃ高いだけに非常に残念です。この手のゲームは英語の解釈の違いだけでも詰まる事があるので私にはどうする事も出来ませんでした。

### 3/5 — Achievements don’t work

*2021-01-03*

Other than that this was a fun game. The achievements, in iOS 14 at least, pop up each and every time you complete a level. All achievements earned pop up this way after each level. Also, they do not seem to save in Game Center. I completed the game (including the final four and the T-800) and Game Center still only shows me completing Parts 1 and 3.

### 5/5 — Hard!

*2020-12-15*

I’ve done 62%. There should be a leader board for bragging rights.  I’m posting your game on my puzzle app blog gottasolveit.

Great job Maxim

**Developer response:** Hi Tom,
Thank you for your interest in my games. Unfortunately I could not find your contact at the release day, I wanted to personally tell you about the new game.  Hope you enjoy it.

### 5/5 — Cooles Spiel

*2020-12-03*

Vom Inhalt ist es ein gutes nachdenk  Spiel 
am Anfang für Anfäger leicht gestaltet und dann wird es immer schwieriger 

Hoffe es gibt bald mehr😁

### 5/5 — If you like puzzle games, buy this game

*2020-11-29*

Good graphics? Check
Good music? Check
Original? Check
I paid like 1,50$ for this game on Black Friday. Unbelievable value for the money.
