This is a new RPG game published by Rovio. Honestly, this is the first RPG game I've ever played on any device, but I'm still gonna make a comment on this as a normal iOS and OS X player.

First of all, the UI of this game is just as good as other games in the Angry Birds series (in which I love the Angry Birds Go! the best). Anyway, there are still some shortcomings in this game. For example, you have to wait for a long time before opening the game, every time. Also, I cannot find a place to log in my Rovio account and sync my playing progress, which means I have to play this game all over again if I download it on another device. This can be very annoying if you have many iDevices.
Secondly, the game guide of this game is pretty long, which requires a lot of patience. The first few levels were pretty easy which you can easily get three stars, and you just click where the guide shows you.
Thirdly, this game turns hard suddenly. I passed every level with three of two stars by just playing once before this really hard level came. I tried several times but my birds just keep dying. Soon, I got bored with this game and wanted to delete it from my iPad even though I just downloaded for less then an hour.
In the end, I hope Rovio could update this game soon and load it on the Chinese App Store. After all, not everyone has a Canadian Apple ID.
