Notes: 
If you make the window full screen you should wait a second for it to load and you'll have to click on the screen before the rest of the controls start working. Also when the timer menu reaches 0 you'll need to reset it by clicking off the object and then back on.

Controls:
WASD - moves the camera up, left, down, and right
QE - zooms the camera in and out
Left Click - selects tile

Basic Gameplay:
Slimes will earn essence when they are in a habitat. Feeding the slimes will increase the amount of essence they earn. You can feed slimes with food you earn from farms. You can build new buildings by selecting an empty tile. To get more slimes you need to build a habitat of the appropriate type. Then you can buy a new slime core from the incubator and wait for it to hatch or you can breed two slimes for a chance to get a new slime core.
