I cant believe you made me do math, 0/10.
Lol really though nice job, I saw you mentioned in a few places its below your standards, but honestly it was fine for what it was. Between the music, the timer, and the submission box suddenly moving the presentation kept me engaged way longer than I admittedly thought it would, and it was fun, and thats what matters! My only suggestion would be similar to the others, trying to adjust the time depending on the size of the numbers in the question, and maybe keeping the submission box from completely covering the button and question. Good job though!
