Good game. Liked the core mechanic of combining blocks into any shape after heating them. Felt like a real forge. The level progression was good, atleast until the rent part started :) In terms of controls, moving the pieces around was simple enough. But scrolling the wheel while holding down the left mouse button was not the easiest of maneuvers. Actually in the first level I thought I had to bring pieces into the right orientation to get it accepted, but learned later that it was not required. Good music and suitable art. Well done overall!
