Congrats on your first game! Love the visuals and interactivity added to the trivia concept!
Sometimes when I got an answer wrong, I would have loved to read a follow-up about it. For example the "elephants can't jump" question I got incorrect. It would be really neat if the game told me "Actually.. Rhinos, hippos, and sloths also cannot jump!" before going to the next question.
Also, sometimes I accidentally double-pressed the button if I slightly walked past it in the corner, and I'd immediately answer the next question (Sometimes incorrectly) so adding a short delay on the buttons after you press it might be useful
I really enjoyed the fun facts you picked for the game! The graphics were well done and the music was perfect for the game. It was really interesting to see the variety of questions and I even learned some cool new factoids!
Nice job!
