Found this game on Kbhgames, love it so much I made a itch.io account! Just saying that it would be helpful to add upgrades to the furnace to make it quicker for player progression!
Thank you so much, that really means a lot to me! KBH Games has been awesome. They not only credited the game with my name, but even added my itch.io widget for Serenitrove on their site.
Edit: Thanks for the suggestion, new Dojo training added to improve smelting speed (only available after Stamina, Power & Regeneration are maxed)
