This is a request, kindly higlight this point, that after one stage new users have to deal with people who uses money in the game. And this will slow down the rank achievments. I don't know how many will like it but here are some suggestions: 1. Make saperate room where people can use their powers like button 1234 and so on. so that if people investing money can show how rich they are in the game. 2. Make saperate room where 1234 will not work and players have to rely on their tanks and falling powers. So that the game should be fair for every single one. 3. Or ask for bank balance during the registration, if they do not have don't let them come to the game, because eventually they will suffer from people who buy stuffs.
