The Cels interact with each other and can identify each other by color. Depending on the color of what they are seeing, they will look for food and if what they are looking at is the color of their food, they will go to it and eat it. If what they are looking at is the color of something that likes to eat them, they will run away and look back to see if what was trying to eat them is still there. If their nutrients are high, they will reproduce, making them a reliable food source if you can balance them You can press the buttons on the bottom left to spawn in different Cels.
This is still in beta and is subject to change. If plants fill up the screen and you are no longer able to spawn in Cels, reset the project. Plants are overpowered right now and I need to nerf them. Feel free to suggest things you would like to see in a future update. (You will be able to play as one of the Cels in a future update) Inspired by Roblox's Terra
