a - There is an autosave that uses browser cookies. It triggers every 30 seconds. What browser are you using?
- Update: I’ve updated the code to use localStorage instead of cookies, which should be more reliable.
b - Crafting is basically the same as Minecraft, so recipes can easily be looked up. Hints and guides are purposefully lacking, partly because that’s how Minecraft was back when I originally made this, and partly because I think it’s more fun to try something and see what it does than have tutorials interrupt.
