Really cool concept that I don't think I've seen before. I loved the character progression. Just a few quality of life things I'd like to see improved - 1) I want to skip the animation at the beginning after the first time! 2) The music gets really repetitive after a while 3) The suitcases could stand out from the passengers a little more. In the beginning it can be hard to see them to jump, though as you get faster and they slow you down less this isn't as much of a problem.
Overall nice entry, enjoyed it quite a bit!
