This is a turtle natural selection thing. I didn't draw the dangers on the beach, but yeah. The turtles are the black dots and the food is the red dots. Press and hold space to pause. Hover over a turtle to view its genetics (excluding its land and water speed). Shift+Green Flag to turn on turbo mode if you want to speed things up. Adjust the sliders to change the environment. Sliders: Reproduction energy: How much energy it takes to reproduce Energy per food: How much energy you get from food Start turtles: how much energy there are at the start Start energy: How much energy each turtle starts with Water move energy: How much energy it takes to move through water (partially, the other part is decided by the turtles genetics) death rate: How likely a turtle is to die on its dash across the sand (lower is more death) Land move energy: How much energy it takes to move through land (partially, the other part is decided by the turtles genetics) Food spawn wait time: How much food waits before spawning Hunger: How much energy is lost (added on) per tick Genetics: Growth rate: How fast a turtle grows Land move speed: How fast a turtle moves on land Water move speed: How fast a turtle moves on water Offspring amount: how much offspring it produces
