First off, I should NOT have to sign up for a forum just to get support/provide feedback on a game. Just saying.
I just started playing this game. It was my second time in the arena.I was in the arena and I clicked on a person I'd fought but not defeated. A window popped up with some buttons but none were labelled and no labels popped up for them. I clicked on the green refresh-looking button to the right and suddenly I'm out 5 gems because it changed the person. I thought I was clicking on the option to refight the person, seeing as I lost the first time. I'm a little irritated that there was no "Are you sure you want to spend your gems?" kind of warning. I was having a lot of fun until that happened. I know it's small in the grand scheme of things, and that maybe I should have read how the Arena works before going in, but c'mon, anything that you can spend REAL MONEY for and that are very rare to come by should let you know when you're about to spend them. Now, I'm not about to spend ANY money on this game.
Otherwise, I am really enjoying this game.
