The treasure chest is seen from above now, like the quarry. Its pile of gems spreads across the floor as you mine, and the gems you mined land all over it.
The crates are drawn wooden boxes seen from above, in their group's color, with the count on the lid. Both are stand-ins: a chest with a lid standing open behind it, and a more dungeon-like crate, are on the way.
Controls now work like the studio's other games: the debug overlay is on the key (or ?debug` in the address), and the sound setting is kept the same way in every game.
TREASURE!
