### Tile Types
## Build Mode
Build mode can be entered by pressing the `b` key.
Build the cursor will start flashing when entering build mode.
Once in build mode, a tile type must be selected to build anything.
Tiles cab be selected with the buttons along the bottom of the screen or by keyboard shortcuts.
The keyboard shortcut to select a tile type is indicated on the button.
To deselect a tile type, press `esc`.
Press `esc` again to exit build mode.
## Tile Types
Tiles start as wild tiles.
The player can use a UI element or a keyboard shortcut to enable build mode.

* Wild tiles are green

### Heat
## Heat
Developed tiles produce heat while wild tiles absorb it.
Every tile has a floating-point heat value which diffuses to its neighbours.
Add a heat map view which can be toggled or cycled to.
It is possible to cycle the view using a UI element.
### Tile Health
## Tile Health
Add another value to wild tiles: health.
A wild tile can accept a certain amount of heat each tick from surrounding tiles.

Diffusion still occurs to move heat away from depleted wild tiles.
### Rewilding
## Rewilding
Add a rewilding mode option to the UI.
In rewilding mode, the player can click on a developed tile to turn in into a wild tile.
The wild tile starts with 0 health.
### Wild Recovery
## Wild Recovery
Depleted wile tiles can recover health each tick.
The recovery rate is based on the difference between the damage threshold and the actual amount they received.

### Journeys
## Journeys
Developed tiles have a chance to generate journeys between them.
A journey instances a vehicle which traverses the map at a constant speed from its origin to its destination tile.
A vehicle adds a constant amount of heat to every tile it traverses.
### Moving In
## Moving In
Residential tiles have two new integer resources, current residents and maximum residents.
Every tick there is a chance for residents to move in to a residential tile if the current number is less than the maximum number of residents.
The initial number of maximm residents per residential tile is 4.
### Jobs
## Jobs
Industrial and commercial tiles have two new integer resources, available jobs and occupied jobs.
The chance for residents to move in depends on there being being fewer occupied than available jobs.

occupied jobs / available jobs .
### Commutes
## Commutes
A resident moves in to a residential tile and gets a job at an industrial or commercial 'job' tile.
The residential tile regularly generates journeys to the job tile, and the job tile regularly generates journeys in the other direction.
### Comfortable Living Temperatures
## Comfortable Living Temperatures
If a residential tile is too hot, people will not want to live there.
Residential tiles have a critical temperature at which the chance of someone moving into a tile becomes negative, becoming a chance that someone moves out.
