Loved the idea, very cool puzzle concept. Art was simple, but effective and while the music did get a little repetitive, it was good (and you had sound settings which is A+ in my book haha)! I did get stuck on the fifth level like a few others here - I thought I'd need to shove her to the other side with one of the platforms, but that never seemed to work - curious what the solution is.
Also minor art feedback, while the blue on light blue is a nice choice, I found it a little hard on the eyes. Not a dealbreaker, but it made some of the text in the tutorial hard to read for me.
All that said, excellent work!
