At first I thought you had to stop Goober from taking your cookies by shooting them lol! Great game, love how you have to start reacting faster when the puppy dog eyed Goober appears to rush your cookie production! This feature helps a little bit with the repetitiveness.
(Don't know why the cursor kinda looks like a gun crosshair (like those super simplified ones you see in some games), probably should have made it a glove hand pointing or something, since you are pressing the buttons and not shooting them?)
