To all of you who want to get it in three days or less, I will tell you it isn't as hard as it sounds. First, start off giving two squares to height, 1 to band, and one to width. To make everything easy, start the first day and earn at least 1600. After day 1, use that to buy two radar squares. Now, buy rocket level 2, and use whatever is left over on fuel. After this day you should at least make it to the moon. (If not, restart.) Use most of your money to buy high fuel and the rest on radar 3 and fuel sucker 2. If you have anything left over, spend it on regular fuel. Watch for purple platforms, and start using your rockets when you get to space. You should make it now.
