Coffee beans!

I have a cool game mechanic idea! 

Coffee beans! But....there's a catch to them.

If you eat them, or drink them, time in the game goes faster for a certain period of time. BUT...if they are GOLDEN beans....time in the game goes SLOWER. Kind of like that episode of Futurama where Fry drinks so much coffee, time moves so slowly because he's moving so fast and saves everyone from the fire. The other catch...to make it more challenging is if you consume beans, your hunger levels drop faster...because you're using more energy.

Like that!
