Hey Liyanah! Well done. I think all of your answers are correct since I got the same answers as yours, however, I messed 8 so after I looked what you have done there I realized the I have misread the numbers, so thanks! The link for the game was cool. I really loved it. The video helped me a bit and I also liked how you had different colors and text size in your scribe post because it really looked organize. Thanks for reminding me the MangaHigh also!
