This game is unfair, the time limit is less for you than your opponent and when your opponent time runs out they are still able to make at least 3 more moves. I was playing the solo challenge with the special edition spaceship which I paid for, had made it pass the first 100 points on my way to getting 500 and the game froze, not only causing me to lose a SE Booster but also the possibility of making it to the end to claim a total of 4 more boosters. I deserve my boosters back.
