- Your first dig is a smaller mound with the piece near the middle, and the old dig in it opens onto the pale seam. A line under the dig view tells you the seam means the artifact is close. Digs grow back to full size over your first few finds.
- Come home carrying a piece and the plinth it belongs on lights up, with a line saying to display it there.
- Step out of the dig and a prompt offers E to go straight back in. No need to walk away and come back.
- Dig near the buried piece and the chips sound and look warmer the closer you get. Dig into the core and it cracks and shakes, and the danger cue joins as the wall weakens.
- There is bedrock under every mound now. Reach it and a tap gives a dull knock and a cold spark instead of dirt: nothing here, dig elsewhere.
- Run a dig long and you can hear the boulder waking up behind the wall, well before it comes through.
- Losing a round no longer makes the next one harder. The boulder's speed, the tap budget and the tunnel's length grow with the exhibits you have brought back, not with the rounds you have played.
- Taking a piece out with you no longer drops the visitor and exhibit counts. They only fall if the piece is actually lost.
- The seam around a buried piece sparkles a little more often.
- The round ledger's button now reads "One more round".
- Digging into the side of a hole now brings that wall down instead of nibbling its rim, so you can widen a pit toward the piece.
- On the way out, W and S now run along the tunnel where you stand instead of drifting with the camera round bends. The keys themselves are unchanged.
- Nothing.
- None noted, but please do let me know if anything issue is encountered!
