I don't know if it was done on purpose, but sometimes the game would keep opening a new tab with this swartag website every time I clicked in the game's screen. Pretty annoying. If it is was an aggressive advertising method, I'd give the game a low rating because that's despicable. As I cannot know if it was made on purpose, I'll just give it four stars and get out of here. It's a good piece of work, nonetheless.
