• Send map data in bigger chunks
• Use binary instead of text
• Use caching
• Use compression
• Use UDP

• Item types
• Each item type is stored in its layer. No more than two items of the same type are allowed for a position
• Dynamically construct new items during the game
• There are rules for which item types can be stored together

During the generation phase, random walkers can live blobs of water. These blobs would gravitate toward each other, forming lakes. Later, dust near lakes could turn into plants, that essentially would be game of life cells.
When the cells die, they would live a pile of dust around them.

These cells could be consumed by other organisms (player and rats).

Later, rats could be consumed by cats.

Both rats and cats form out of the dust.

Player should be able to push solid items automatically.
There should be a mode that allows to push non-solid items as well.
Same goes for pulling. It should be possible to pull some items.

Add electron head and electron tail nodes.
Then, add constant electron head, constant electron tail and wire nodes.
The later would be generated as ore, with electron heads being surrounded by electron tails which in turn will be surrounded by wire nodes.

As electron heads travel through the wires, they generate energy which would dissipate in the surrounding environment as heat and/or light. This could be used to grow crops.

Move all the generator code to the generator class. If you feel like it, make generator an interface/abstract and implement/extend it.

Hunger would slowly grow. Agility would decrease as the player walks and as hunger grows. Health is decreased if the hunger level goes too hight. Player also gets slower as agility goes down.
Player should be able to each cave plants and cave rats to decrease hunger.
Monsters and traps (to be added later) should also decrease health.

If health gets too low, player dies and the game is lost.

Like eat food, throw an item out, install a trap, use a pickaxe.

Two stage use process:

1. Select Item from the inventory
2. Apply it (possibly with some modifier)

Instead of having add(Item) and remove(Item) in the World, we can make it so that items are automatically added to the world when they are instantiated.

• Add ores
• Add durability for pickaxe
• Add strength level for walls

Use a separate branch, Luke!

Chunks?
Quad trees?
