Hi, just finished checking out your game. It is a massive work for a jam game, really good work here! I love the hair's movement as it remembers me a lot of Celeste's one. As some comments pointed out, it can be a little dispersive at times, and I love metroidvanias, but having the ability to go almost anywhere (due to the gravity flip mechanic) is what made it a little bit confusing some times. Apart from that it's a really cool concept and really well executed as well. Really a cool project, you should develop it further after this jam ends.
Again, massive work, good luck with it, you deserve it! <3333
