you may have to answer the question twice, so if you think you've got the right answer, then put it in, hit respond, then if it doesn't change background in the next few seconds, answer again. I'm not entirely certain if the hints work.
this came to me on the spur of the moment, and I made it just a couple of hours, so it may not be as good as, say, https://scratch.mit.edu/projects/249146589/ (my platformer that you should play)
