A nice little game! I liked the gameplay and cute characters. Also the process of forging feels nice :)
The only things I'd love to have is some more guidance on how parameters work, so that my work wasn't so random :D I also thought at first that I could only create a properly looking sword, but later it turned out that I could play the game like Tetris sometimes. And it would be very helpful to see the current request of the knight while you are actually forging!
A good game overall :)
