Woo managed to serve 11 customers. It took a couple plays to realize that "blue neutral face" means "kinda cold" and "red neutral face" means "kinda hot", maybe I just didn't realize that there were the two different colors of neutral faces because of the pace. This could be improved with a slightly different icon for the neutral faces so that the difference stands out more. The pace was pretty challenging to keep up with, I'm not sure what the "best" you could do would be. I think that it would be good to give an extra life every 10 satisfied customers so that you could potentially keep going, since random spawn rates and satisfaction wait times are going to cause you to lose eventually unless you're really lucky. The extra lives could let the game last a bit longer. But solid mechanics and good graphics, no bugs that I could detect, interface worked really nicely. I liked that you could fill the water bucket and then set it down so that it was ready to use!
