Fun game that feels great to play, with an absurd amount of polish for 48 hours. I wish there had been some other mechanic to expand on the (really cool!) mechanics that were already there though! My strategy was, whenever I received an order, I would just put the appropriate number of ores in the furnace and process them as a batch. I never needed to worry about ore burning and got up to 1200 really comfortably before I got bored and quit. Would have made for a more interesting push/pull if the game ever threw some wrenches in my plan.
I feel like there's a ton of potential here, hope you all continue to work on it.
(p.s. my left hand hurts right now, so thanks for making a game I could comfortably play with just my right ^^)
