### 3/5 — Lost in a lost world

*2023-07-27*

A great game let down by some bugs. Can’t save. Screen jumping up and down. Five stars when all fixed.

**Developer response:** Please let me know which device and iOS version you are using. The commands "SAVE" and "RESTORE" appear to work fine. Please let me know what you mean by "Can't save".

### 5/5 — Yes it is Zork, except Zork came from Dungeon

*2019-10-11*

Kudos to those who realized that this is Zork.  However, this was not taken from Zork.  Zork was a commercial personal computer version of the already existing Dungeon game from the minicomputer world.  As a kid I was playing Dungeon at my dad’s work before the Apple II was even wide spread and before Atari and Commodore computers were even for sale. This is a fun nostalgia game to play on the phone !

### 1/5 — Rubbish

*2015-06-24*

Crashes on startup. Don't waste your money.

**Developer response:** Hi Claire, sorry about your experience. Please let me know what device you are using and  I will look into this.

### 1/5 — iDungeon

*2013-05-16*

I just paid $2.99 for this game and it does not work at all. The black dos text screen comes up, but there is no way to get a keyboard and type. No choices at all. Screen is just dead????? Can this be fixed, or, I would like a refund.

**Developer response:** Hi, sorry about your experience. In case your problem persists, please let me know which device you are using and I will look into this.

### 5/5 — Help

*2012-01-08*

I Love the game but im on a 2nd generation ipod touch so how do i load a saved game?

### 5/5 — Love It!

*2011-09-12*

I, only being 14, originally played this game on Call Of Duty Black Ops under the name of, "Zork" but this version is so much better purely as now I can type using an actual keyboard! I only have one complaint which is, why does it always scroll to the topp every time you type anything? Please fix! Never the less I love it!

### 2/5 — Aww.

*2011-02-18, version 1.3*

I had an iPod. I dropped it in my basement. The screen completely cracked on the cement floor. I hadn't synced it. I got a new one. I wanted this app again. It wasn't free...

### 5/5 — Amazing.

*2011-01-30*

This is Zork, yes, but it was originally called Dungeon, until the people who made Dungeons and Dragons said it was copyright or something. 
Either way, this is quite possibly my favourite app.

### 5/5 — Awesome game

*2011-01-16, version 1.3*

I say apple should allow app development tools and these people should make a full pdp11 emulator cause that would be really awesome. Though this is as close as we can get now I still love playing dungeon but I can't get back into the game after accidentally quiting!

### 3/5 — Is This Zork?

*2011-01-16, version 1.3*

If this is Zork then it's a huge game! It may literally take you days to finish it. You definitely need to draw a map to keep from getting lost. I'm not kidding. Good luck!
