It would be nice if there was an easier method to farm clams. Walking through water and digging them up can be a bit bothersome after a while.

My suggestions:

• Allow harvesting them by using the Chalcedony Knife. I suggest a right-click to get the clam without having to dig the sand
• Add some kind of farming block or net like in this picture: http://de.wikipedia.org/wiki/Datei:Oyster_culture_in_Belon,_France_01.jpg
  • Maybe even add an upgrade to improve the chance to get princess clams :-)

Thank you for your comments!
However, the idea of some of the following have been implemented already.

By players right-click without holding anything, sand is taken out a clam. This has been implemented already.

In addition, a new tool that can be "range harvest" the clam, has been developed currently. (It will correspond to not only clams, such as tea tree, the plant to be operated by right-clicking.)
However, it will take some time still to release.

In order to grow the clams, you can use the "incense of clam".
In addition, the Princess, appearance rate will rise when clam is overcrowded. Appearance rate can also be changed in the configuration.

Blocks for aquaculture will not be added perhaps.
This is because the idea that (similar to some famous large MOD) one block to control the system is a typical and universal. (Sure I think it's good idea.)
I would seek a different method.

Another reason is due to the Princess is an magical element.
By applying a magic, or a magical items is administered to a sand containing the clam, I have an idea for that Princess occurs. This is still in development.

(By the way, in Japan, clams are amulet for girls.
Shells of two pieces will match perfectly only by the combination of one. In addition, it is tightly closed.
That means amulet of protection, or amulet of love. )

In version β1, high pruning shears of chalcedony has been added.
With this item, you can harvest the following items in the range.
To be used by right-clicking the object.
・Clam
・Tea leaves
・Cassis fruit of fruit and camellia fruit
・Yuzu fruit
・Vanilla crop

Default range is 3 × 3 × 3, the range is increased by the addition of enhanced efficiency.

In addition, in the current version, but does not have the equipment to grow the clams,
Clam in the sea or the beach will promote growth.
