I played this game on stream: https://www.twitch.tv/videos/2565553540?t=00h01m01s
I didn't get very far in the game because I couldn't figure out how to play, or messed up the tutorial or something. I started a dig site, but I was unable to find any artifacts. Then since I didn't have the hammer to make more dig sites, I was stuck. I tried driving in the desert but it was all empty..
Perhaps have more hints in the game, and/or replace the hammer during the early stages (maybe some NPC offers another one?)
