Defender is a pretty basic castle defense game, but it is fun to play. With the same playing field and a rather limited selection of monsters it can become a bit boring the more you play. While the game is free there is also a cash shop where crystals and cash can be bought unless you prefer to grind for these valuable resources. A nice game to play every once in a while, but it soon grows tiring.
Gameplay: Addictive at first, but the lack of variety can make it a bit boring later on.
Graphics: Very polished, but could have used some more variety.
Sound: The sound effects are good
