For this week's challenge my mind immediatly went to something I misinterpreted the first couple times while playing Deltarune's Chapter 2. While running across the road with Noelle, heading up with her behind you makes her look like she's rushing YOU upwards, due to not having a true "back" sprite while running up, however Kris does turn all the way around so it just looks like she's rushing them up as fastly as she can to get them out of traffic. They also move the same speed and directions, so it's even more difficult to tell apart.
An example of this that's easy to see is in 2 Left Thumbs' video, here: https://youtu.be/zGe1MERbic4?t=252
I'm not sure if I did this week's challenge the "correct" way but it was fun either way!
