It is a great game and truly worthy buying.
The controls are very simple and easy to remember. Your powers are balanced with the difficulties of the game, and it is fun to use your creativity on how to kill the foes.
Graphics, really cool, I loved the atmosphere you feel at Star Wars. Sounds are great. Enemies are easy to kill. However, they come on strategic formed groups clearly gathered to optimize the battlefield.
In some points, it gets frustrating not kill a boss or pass a challenge, but relax, as soon as your abilities get better you will pass and laugh at it.
A bottom line: Buy and play.
May the power be with you.
