Very addictive!
It's a good game. Don't believe in those who say the game is repetitive (read the title of this review) and the music sucks. The music is totally appropriate for the game. Even then, you can still turn off the music in the options and instead listen to whatever you like.
Now, about the gameplay... very addictive. Seriously, it's addictive, not repetitive. Instructions should tell you what you should do in the game. It shouldn't spoonfeed you about everything inthe game. It should introduce you to the concepts of the game. Deal with it, those who are so dumb they rate this game very low cause they can't understand the instructions.
One thing I would like to criticize is the fact that if you lose, whether you saved or not, it would take quite a while to take you back at the menu. Also, it DELETES your save. I suggest to cut the time it takes to take you to the menu. Better yet, you can code it in such a way that you can go back to the menu whenever you want. Also, let the save stay when you get game over. Other that that, excellent.
