Good job, this is a nice little game you've got here. The game design is simple enough that I understood right away how it worked, and I really liked the way the food and buttons slid up before you. My primary critique, other than me not being able to tell the difference between good and infected pizza, is that there isn't much challenge to the game. It's just "is the food good: yes or no". I think adding some sort of timer or penalty for waiting too long could make the game more challenging and keep the player engaged longer. Perhaps the food is coming flying in and so you have to quickly decide what to discard before the food reaches the person and he eats it.
Overall though I'd say this is a great first jam submission, good job!
