Thanks so much for the feedback!
I can see why you would quit in those conditions. Basically, the metal detector can dig up other tools, like the Primitive Antenna and the PNY GeForce RTX 3050. These can be stacked with Vanilla Humans on the Attuning Table to produce specialized workers, who can use the tools they studied to advance, and reach the end game.
Again, thanks for playing the game! :)
