This is a good idea, the difficulty curve works well as you get used to the game and soon have it turn to frantic swapping and checking, I do feel like when checking if the answer is valid and it's wrong it should just take some time away not instantly game over in my opinion (That does lead into a good easy and normal mode though so maybe think about that after the jam ends) the music and sound effects work well and the art is basic but it should be for the pictures, the background should have something going on but I can understand that being distracting
