Warping for everyone
My sugguestion is to make the "move city" option available to buy with the in-game currency in addition to coins. Your first reaction may be "Well how is this supposed to lead to more coin sales??" Glad you asked, it can lead to more coin sales by costing alot of in-game money (maybe 100k+ cash for one sub move). So people will still be able to warp without purchasing coins, but it would also encourage them to buy coins since it would take a while to save up 200k+ cash for just one attack. Again, this would give everyone the opportunity to try out warping without having to buy coins and see how fun it can be, and if he likes it then he would eventually be inclined to purchase coins for warping. Everybody wins!
