An enjoyable game

I enjoy this game, it's a little different than most of the find-the-hidden-object type games out there. Unlocking new portals is the most fun, as you have to interact with the new scene by solving puzzles and finding objects in other scenes to assemble. I find it challenging enough to keep me interested, but not so hard that it gets frustrating. And there are actually a good bit of opportunities to earn crystals rather than having to make in-app purchases. One of the only downfalls I've noticed is that some objects are utterly impossible to find without a hint because they are almost entirely hidden behind something else, only showing the smallest unidentifiable sliver. Another annoying thing is when they tell you to find the gold mask for example, but it's actually green because they've changed the color to hide it in a bush. Or to find a ruby where they've removed the red color, so it's just a shape. I wish they'd come up with an alternative to hiding objects that way. There also seems to be a bug in the friends area, so I'm only able to add new friends once after each game update. After that it tells me I've reached my daily limit of friend requests in other games, which I have not, and to check again tomorrow. But the next day, it tells me the same thing, and so on until a new update comes out. Overall, still an enjoyable game.

Twin Moons Society Hidden Mystery

This game popped up as an ad several times when playing something else, so I finally decided to try it. I am somewhat addicted. Lol It is very different than any other hidden objects which I like . The only problem I have is I didn't find any info on how to start. It was basically trial and error. I made a lot of errors. Some of the portals are very difficult and at times and a bit frustrating. Some of the things you need to open the portals shouldn't be so hard to get for instance the orchids in the entanglement puzzle. I am not very good at it and when I finally do, I don't get the one thing I need. I like the challenge but at the same time I can understand why some people quit playing. As for me, I will keep trying. For now anyway!

Too complicated, story is intrusive on gameplay, designed to make you constantly need hints

I love hidden items games but this one was frustrating and not fun. The items are hidden in ways that make it impossible to find them without hints, like putting them into a darkened area of the picture and making them the same color as the surrounding background. Even after using a hint there were items I never could see -- I clicked in the area of the hint to get them but never found them myself.

The story was too intrusive on the gameplay with new quests and things constantly popping up. I played for a few hours and still don't really know what I was supposed to be doing.

To be a fun game they should try to simplify and streamline it. Also don't make hints obligatory to advance. A game is no fun to me if I can't conquer it without constant hints.
