I don't like to be rude, but, this game is ridiculously buggy and I cannot play it at all, period.
In my first attempt of playing the game, everything had ice physics and I couldn't place anything down on the anvil without it buggering off to the moon.
In my second attempt, customers didn't say anything , making it impossible to fulfill their requests.
And in my third and final attempt, The hammer didn't work at all. I heated two iron ingots fully, placed them on the anvil and tried to hammer them into a blade and... well... nothing. I tried rapidly clicking, nothing, I tried holding it down, nothing, I tried clicking periodically, nothing.
Additionally, the game lacked any audio whatsoever.
