It would be great if u added a loan service on game I.e taking loan of elixir or gold n then making the player repay it later. This would be great as it would help players to get resources when in need like while upgrading walls. Also u could limit it like 2 time per month n that the intrest increases if u delay n if delayed more than 2 weeks then u wont be able to collect so resources from collectors while the collectors will continue generating resources.
