The game was alright but I just uninstalled it because some aspects just turned me off. I felt the combat was a little half baked, but then I felt it was really ridiculous that the "watch ad for free gems" didn't work - every time I clicked it my game froze and I had to force quit. I tried like 5-10 times after trying various things as well and it drove me crazy so I just uninstalled. It felt intentional, like they were trying to get me to pay for gems and I was not too happy about it.
