Interesting game, but a bit too short! I loved seeing the idea but it could really use a few more levels to flesh it out. In fact, maybe it's a bug? I never saw the level in this page's screenshots with the two portraits...
I also would prefer if the controls were not reversed when you are upside down. It's a bit confusing and I always walk in the wrong direction when gravity is flipped.
I like how the princess is an unusual protagonist in these games, but I'd change up her arms! It looks like she has either no arms or she's always walking with her arms to her side like she's T-posing.
Overall, it was well executed, only a bit short. Good job!
