The reason why I give this game 1 stars
The levels get very hard for me and this just makes me unhappy and just want to get rid of the game and you have to complete 10 levels so u can get free mode. Just why after you know the basics you should be able to play free made so it will show you the help tips for reactor cooling earthquakes etc. but I rate it 1 stars. I hate how many levels you have to do just to get free mode. DO NOT GET THIS GAME ITS TO HARD TO DO AND WAY TO MANY LEVELS. developers I hate you for making this to hard
