## J1 (docs/WORLDLETS_DESIGN.md §10): the cliff tunnel, in single-player. Dig
|
|
## the seam on the Valley clifftop with the antler pickaxe (a lesser pick
|
|
## won't do), go down, dig six stretches (each propped before the next),
|
|
## light it, walk down it, out through the sea cave to the Cove, and back up
|
|
## the same tunnel to your chest at home. Each worldlet keeps its own save.
|
|
## Run: godot --headless --path . --script res://tests/test_tunnel.gd
