I love the concept here, and I think you're already more than half way there to create a great mysterious Christmassy atmosphere. Just a bit more audio and a few more visuals, and the vibe will be perfect. But I already really enjoyed it as is! Running around, slowly learning to optimize my production line and then feeling really good about myself once I got everything properly prepared and am able to create 4 lights in a row. I only really miss a bit of a challenge here. You could make it timebased, but I'd also love to see more 'difficult' recipes for special lights in which you kind of have to puzzle to gather everything needed, or something. Anyways, I really enjoyed playing and I loved it when the entire screen lit up with lights in the closing animation. Well done on making a cozy game that has me yearning for mystery!
