Spring Cleaning! This update doesn't actually have any new features, and instead is all about bug fixes and polishing. The last update featured a new smelter, which had a few minor bugs, and frankly it worked too slowly for most players to appreciate it. Apart from smelter improvement, things were fixed and improved in lots of little ways, based on a list of minor bugs that had not be addressed yet, and a bunch of small improvements that could be made, based on recent player feedback and (indirectly) suggested by some recent videos that featured the game.
Feel free to post bug reports and other feedback on the Steam community site or by using the in-game button on the pause menu to Send Feedback (via email). Thanks to everyone who has emailed with feedback and bug reports!
