Do NOT waste your time with this game! It has a lot of potential & nice graphics, and it used to work fine, but now it can't sync & it literally crashes every 30 seconds. I got it when it was first on the App Store & I got to the top level & opened up the sandbox area (when I did that, it started getting laggy after ~30 min of playing), but then they "upgraded" the game and added a rift, it just can't handle itself anymore (maybe combined with the open sandbox areas like Winter's Teeth?).
The developers have known about this issue for MONTHS now, and refuse to do anything about it. I'd contacted them for help several times, but they kept blaming my iPhone 5s, or Facebook or anything else besides their app, even though it's the ONLY game on my phone that crashes all the time! I waited a couple months for a new upgrade to fix the issues, and it's EVEN WORSE now. Now I can't even go up to the tower to get my daily watchers without it crashing. I would have deleted the game already, but since I'm at the top level and it can't sync, I decided to leave it on my phone for now and wait for them to fix this sh*t, but they don't seem to care. That's why they only have a few reviews out yet the game has been out for almost a year now...
