Interesting proposal, I liked the overall concept and mechanics of the game.
However, I found some mistakes that really subtract quality from the final product.
Playability and game feel is what makes a game. While I found your mechanics to be quite interesting, the execution is a bit lacking. I find myself using the earth character most of the time, except when I have to go through dead trees; and I didn't even get to use the girl's powers at all, I just used her to walk around. Also, the movement system feels a little tedious and rough, just by polishing it the experience would be 10 times better.
I also felt like there was no real challenge, it's like I just had to find the way to the coffe place changing characters from time to time. You should spice the puzzles a little bit so the players gets more involved to continue. As the game is short, this is not a big problem, but it can become a problem if you want to expand the game in the future.
The final cutscene is quite cool though, I really liked it! 😊
Keep working on your project, with some more time to polish its features you can make a great experience from this concept! 😁
