Nice game! The core gameplay is really good and fun, and captures the forge atmosphere and catering to impatient customers well. There's just a few things that are making this a bit difficult to play. Would have liked more time between things in general. Slightly more patient customers, atleast in the initial levels. Especially the gap between the melter being ready and blowing up was too short. The blowing up itself is fantastic though. Not just from an effects point of view (which is great too), but it really gets you serious about the game. Another thing I would have liked is to stash items somewhere. Like you made a mistake in tool selection, or the customer left before you could service them. Maybe just 2/3 item slots. Often I was saved when the order didn't get done in time, but the next customer wanted the exact same tool. Building a tutorial for a jam game is no small feat, so kudos on that. Overall well done!
