The Game speaks LIES and so does its CREATOR!
The Centennial Pickaxe, very real it is, the Legends speak of its appearance as does its name,
And The Stone, too weathered it seems, so much so, construct of clay overcome its strength.
(Golems can break the stone, which makes you unlock the Pickaxe at depth 100)
(PS: The outlined tiles are un-interactable by everything, golems included)
(PSS: Tiles become un-interactable randomly, though with a higher likelihood the deeper a tile is (the game is probably trying to spawn the sixth block and panicking))
Also saving is a little broken:
Golems went *poof*, along with my resources (+essence),
and un-interactable tiles' appearance are reset back to Grass. (still un-interactable)
The other upgrades were kept though (pickaxe included).
Edit: After some more reloads, it seems like everything saves correctly, but my first save didn't for reasons unknown?
