Gamification sounds in Course Mastery

Hi Khan Academy! I love the little sounds when you get questions right, and level up mastery. I'd also love to see an encouraging sound when you get questions wrong—something victorious, inspiring, motivating when you get questions WRONG, to help you realise that that is when your brain grows the most. This is inspired by platforms like Duolingo, where sounds play a vital role in the game mechanics. In general too I'd love to see a more gamified experience for students in Course mastery. Please make the exercises so irresistibly appealing to practice on!
