Use the arrow keys to move around. You are the green cell. If you touch another cell, either you eat it or it eats you. Blue (normal cell): If you are larger than the cell, you eat it and gain its size. If you're smaller, you're eaten! Red (hungry cell): The cell always eats you and subtracts its size from yours. It also is typically pretty big. Yellow (passive cell): You always eat this, so hope for a big one! Magenta (inverse cell): If you are smaller than the cell, you eat it and gain its size. If you are larger, it eats you! If your size is less than 5, you lose. If you eat almost all the cells, you win!
This is loosely based on Agar.io, a pretty cool game about cells. Due to the limits of Scratch, this is not as advanced, but I think it's pretty interesting. Hope you like it!
