This is a simulator of cutting veggies...Press 1,2,3,4 for mouse edition and a,s,d,f for keys edition...pressing these keys for both editions changes vegetable. Press Space key for chopping in key edition and click in mouse edition to chop. THIS IS NOT PERFECT! This isn't perfect because the chopping is actually a stamp of a color. If you click or press space outside of the chopping board, it will stamp the light brown color there too. Also, the key edition knife stamps from the inside of the knife. The back inside part of the knife is where it will chop from and not the tip or front.
