It's just got really great atmosphere and simple, but addictive gameplay. It's one of those games that has such a mood to it, I just want to play more. Similar to Bastion, but the setting is a lot less cartoonish -- feels much more like a simplified RPG. Again, I think it's great on the mobile platform because you can play it in quick bursts and feel like you're progressing. It's a wonderful way to spend about 20 or 30 minutes at a time. I also think the sound design in relation to the visuals is quite beautiful. Again, I'm a sucker for games like this that create such a strong impression with their mood. I also love hack and slash, so this seems to be a nice new take on that.
