The objective of this game is to serve the customers which ever slushie they ask for. They have three choices to choose from: green, pink, and blue/grey (ordered from top to bottom of screen). You move the waitress with the arrow keys and you get the slushie cups filled (also to give the cup to the customer) by using the space bar.
So when you start the game, you’ll find the that there are three, long stone counters in a row, each one has a slushie machine in at the end of it. The waitress, you, will be at the top counter, looking away from the slushie machine. Customers will pop up at the way left of the screen and you’ll find a bubble next to their heads that has an image of which slushie they wish to have. Use the up and down arrow key to stand in front of the machine and then use the right arrow key to face it pressing the space bar to get that flavor in a cup. When its filled turn around and move to stand in front of the correct counter and press space bar again for it to slide down towards the customer.
