Hello, the creators of a wonderful game of kets! I would like to offer you to add a very useful and interesting function to the game. The essence of this function lies in the fact that for gold you can improve the details on a star. The player has a good iron detail, but it is already on military details and using this function, you can improve its detail to military quality, but in order to improve the detail to the next quality, you need to pump it to the last star of its etap and then again, for gold, improve it to one star's military detail. The more expensive it is to improve. I hope my idea will please you and will appear in the game. And I also hope that you understand it.
