Why not add a pet system that helps attack but make pets incredibly expensive or hard to get ... then make that you can reborn the pets and level up the pet and give items to the pets and have different races of pets ... making it a endless battle XD
maybe add a way to promote people faster ... like a system ...
if worker makes 20k + then promote to senior worker... instead of having to find the person since everyone watns to go to the gym and stuff
