Very poor user interface with no guidance


After having to wait on the opening "Continue to game" screen for 10 minutes for the fix to the game to download per G5's instructions, I finally was able to get to the opening scene. (Note to G5: If you're aware of a problem with your game that makes it unplayable, how about actually fixing the game and putting out a new working version in iTunes instead of just putting a note in the iTunes description describing a workaround that some people may never see.)

The user interface was very unusual and there was no description as to how it worked. I tried for a few minutes to try and open the door (or whatever you were supposed to do in the first scene) and when I wasn't able to progress I decided to delete the game and move on to another one.

Different but enjoyable


A fan of all types of hidden objects games. This is one you can play without the sound on, for instance at night when your partner wants to sleep and you want to play. Also good to play when you don't want to think or fret about what to do next. Or when you want to listen to a ballgame while playing. Plenty of helps and hints. What more could a person want?!

Won't open


I paid for this app and it will not open! Do not buy this app until they fix this!!!

It works now. I love the game but am a little irritated with the character conversation interruptions which slows down the play. You are searching for an object and a conversation pops up and you have to click through these to get back to searching for objects.
