I think you should add an ´Buy Multiplier´ with what you can buy 10 and 100 of things,also i feel like the offline mode is too op,make it so that it lasts a specific amount of time and so that you can upgrade it,i fell like its a good idea because players can just leave the game and play another game and they can have like 1 server and if they come back in days they will have more that a million.Thank you for reading this.
