A very simple premise with some nice pixel art.
Two improvements I would suggest:
1. When clicking "play" the player should see the first item change before their eyes so it would act as a tutorial of sorts and it would be easier to play the future levels.
2. When you answer wrong, highlight the correct answers so you know what you missed.
Even though small in scope, since it's a fully finished project and no technical problems, I think it's a good submission!
