Very cool game :) At first it was a bit confusing because I bought multiple recruits, but they visually all overlapped, which made me think it was bugged.
I think it would be good if the caravan would not automatically keep moving after visiting a city (or at least have the option to turn that off). When I leave the city the first thing I try to do is stop the caravan from moving, so I can group my old and new units together, figure out the equipment etc. One time I tried to do this, but in the two seconds the camel had to move it had already drawn aggro from enemies that had spawned right outside the city.
edit: I don't see music credits. Who was it made by?
