Sorry about that - the last 4 hours of dev time were a blur, and one of the things I was supposed to do during that blur was add more resource nodes. T_T
In case you missed it (It's unclear as I didn't finish the art assets in time) the little red Godot icon on the bottom left of the forge will incinerate things and turn them back into resources if you shove things into it.
I'll have to learn to keep my scope a bit more reasonable next time around. ^_^;;
And thank you for playing it :-D
