Use WASD or arrow keys to move. Press p to pause. Eat objects smaller than Pico to grow, but avoid larger objects, as they will make him shrink! Shrink too much and it's game over! If an object starts changing colors, it means Pico has just become big enough to eat it. You can also view 'The Menu', which describes all of the things that Pico has eaten. In this version, Pico starts at a subatomic size and will grow larger than any cell!
There is still the same food from Pico Attack 1.7, But I changed color of every food except for the Rough Endoplasmic. In the menu, If you want to go back to the title screen, there is an X button instead of a back to title screen button.
