Pretty cool concept, the rate at which the orders come in is well balanced. If you want to reduce the quiz-like feeling, instead of having text in an order, you could have a picture of the crafting table with the pieces on it. Also, needing to select which one I'm responding to interrupted the game flow, so having my response be checked against every answer would make it flow way faster, since I need both hands to type, so I can't use the mouse at the same time. Keep at it!
