### 5/5 — TURN OFF GAMING MODE

*2026-07-09*

The game did not run until I turned off game mode! Otherwise it’s a mid port, worth the money if you don’t feel like lugging a laptop around to play. Definitely prefer the PC version but this’ll do for my lunch break.

### 4/5 — iOS26.5 it works!

*2026-06-20*

Учитывая что YNOproject так и не оптимизировал Yume Nikki для смартфонов, то это просто идеальный вариант для iPhone. Отлично идёт на iOS 26.5! Крайне редко, но бывает что не срабатывают кнопки, но редко и тем не менее версия вполне играбельна. Ещё бы Yume Nikki: dream diary (которая 3D) на iOS или Mac, но как говорится сны и мечты.

### 1/5 — crashes

*2026-06-18, version 1.0.7*

### 1/5 — Doesn’t even start

*2026-04-19, version 1.0.7*

### 1/5 — Scam

*2026-03-23, version 1.0.7*

### 4/5 — Needs to be Updated

*2026-03-21, version 1.0.7*

The game crashes and is unable to run on new iPhone devices. Please update it.

### 5/5 — Yume nikki

*2026-03-19*

Я рад что Yume Nikki портирована на телефоны как на айфон так и на андроид, хотя только недавно узнал что она есть в принципе на телефонах, а не только пк. В общем купил не сразу, но дождавшись купил и как и на пк я ею очень доволен, управление хорошее не скажу что очень удобнее, но не вызывает дискомфорта, багов никаких не заметил и думаю что дальше будет так же отлично.
Люблю очень эту игру за атмосферу и её музыку, кто так же любит сюрреализм и мрачную, атмосферную и местами спокойную музыку то советую к покупке

### 1/5 — does not work

*2026-03-07, version 1.0.7*
