READ THIS! Click green flag twice and you can mine through the furnace window! This is the first game in a while not about me. If I get a lot of feedback I'll add upgrades and other things. I hope you like it! You shouldn't use turbo mode. How to use furnace: First mine the blocks by clicking them. They will come back after 10 seconds. When you open it by clicking it you will see 3 slots. The top one is where you put the ore. To put the right ore in click the slot then click the right number. Bottom one is where you put coal, just click that one. After putting in the coal and ore the smelted ore will pop up in the right. It'll just disappear after 5 seconds.
Lists and lots of variables.
