Furnace is Working! (Patreon)

Here's a quick clip of the Furnace in action! Right now Acorns are the only source of fuel you can use, but I'll also allow you to convert your Log resource into fuel from the workshop. 

Dropping fuel into the Furnace will extend it's active time. You can tell when a Furnace is running out of fuel visually. The coals will start to dim, and if it is smelting something the smoke will slow down.

If a Furnace is active it will start smelting it's contents. If there is at least 3 of one kind of ore inside, starting from the highest quality ore downwards, a bar will be produced after about 15 seconds.

You will be able to use bars to upgrade your tools and craft future items.

NOTE: If Oak Trees are planted nearby it is possible for Acorns to fall directly into the Furnace, auto-igniting it.
