you should add a feature where the more you make things you can make them faster, which a lot of people are suggesting BUT! you also start making them with better quality (quality=better item=profit)
dear diary: today a couple of musketeers came in and asked for toy swords, i think there twins and i think they wanted to play with the swords which makes me wonder if there real musketeers also, my blacksmith, bob, looks depressed i think i'll cheer him up
just shut up monkey god haters, we get it but the sacrifice will give it new powers, imagine all you're towers in one super tower, now i wonder where i could get one of those OH WAIT!!! WE HAVE A TOWER LIKE THAT BUT NO ONE USES IT BECAUSE OF YOU HATERS!!!
