Haven't seen a quiz here on Trijam before, sweet idea! I like them small and big animals! Thanks for correctly attributing the images you included.
On my machine the CPU usage was not exactly high, but my GPU temperature (if I don't mix up the sensors that is) went skywards. After giving my answer to the second and third question I didn't get to see if it was correct and was presented the third one immediately. At the end screen the overlay indicating the wrong and right answers was visible, and clicking to continue did nothing. So you might look into the technical side of things some more.
