Super fun, very much enjoying it. I ran into a game-crashing bug though: when putting in the final mana gem for expanded storage research, the screen goes black and nothing happens. Here's a screenshot of my factory set up. I'm on Chrome.
Very sorry for that! Already released the v1.3 emergency patch, just reload the page to activate, fixes the bug! Again, sorry the inconvenience. (￢_￢;)
