i think a good dea would be that you are able to laybye towers so you can put money towards it that way you could buy the thing you ant without people taking all your cash and i should cost 15 or somthing gems to laybye somthing that way more people will buy gems please take this into consideration i would love this
So when you want to buy or upgrade somthing you dont have enough money for you can laybye it so you put all the money you have into that that tower then you just keep adding to it untill you have filled all the costs then it will start to upgrade
Yeah, sorry but not a good idea. Everyone would just put their gold away as soon as they get it. Instead of saving up 2 mill they will just pay 100k each time and then it will be even harder to get gold.
