You have been a barista for about half your life. You've always loved the job, as hard as it can be. Sure, there are some downsides, like dirty cups and spiteful customers, but the excitement of getting your ratios just right, the nuances of the job, have always been enough to ignore the downsides.

Until recently, when your boss decided to replace you with an automatic coffee machine that does most of the work for you. Well, they can't really replace you, thanks to the unions, but your job has been reduced to pushing buttons. But the most frustrating thing is that even with all the fancy tech, this stupid thing turns out to make simple things hard. And it can barely last a day before it overheats. "Optimizing"? More like "spending hundreds of dollars on a useless piece of plastic".

Mix various ingredients to fulfill orders placed on the right side of the screen. Use the left and right arrows to move the cup conveyor, and the number keys 1, 2, 3, and 4 to pour liquid into corresponding cups. Move the cup off the conveyor to either complete the order or discard a cup. The machine has a fixed capacity for the day, which decreases with each move of the conveyor. Get as many points as you can, score over 100 for a good ending.
