Pinyin vs Zombies - A game for learning Mandarin tones

[Head Start]

I hope it's okay to post this here! I just finished this new app, it's a simple game where you swipe and slash, a la Fruit Ninja. Zombies approach and you tap on them to hear a Chinese word. If you hear the first tone, you swipe straight across. If you hear the second tone, you swipe diagonally upwards, etc. It's a way for new students to hear the words and try and identify and remember the tones by following the tone direction with their fingers.

Would love to hear what people think!

It's only available for iPhones right now on the app store: https://apps.apple.com/us/app/pinyin-vs-zombies/id1493511623?ls=1
