I have tried to play version 0.0.7, and have come across a few issues. When trying to make a hammer head for a one hand hammer, only the blades cycle through. When trying to put 3 ingots on the anvil, the third ingot will go into and anvil. If 3 ingots are displayed on the anvil, the hammer noise does not sound and the ingots do not change into a weapon.
That being said, I really like what you have done with the game. The touch added to the dark crystal was awsome!!
