Everything moves at a calmer pace: every animation runs 1.6× slower than before.
Imps leave a crate one at a time, half a second apart, climbing out over its open door before they turn for the quarry. They head straight for their column instead of detouring past the hole.
A crate's door bangs open when it lands and stays open until the crate is empty.
When a crate is sent, the ones behind it slide up their lane instead of jumping into place.
Done mining, an imp stops at the hole's rim, hops in and shrinks away as it falls.
The chest's edges are clean, and the white rim around minable tiles is gone.
TREASURE!
