I feel like there was a huge missed opportunity for “linking” the slime types (say, fire + plant) and exploit their combined powers to solve puzzles, which would fit the theme to a tie.
I got stuck multiple times while moving around (once I grew while in a narrow tunnel and had to force restart, another time I just somehow managed to move and stuck myself). The plant’s “power” to walk over trees needing to be of a certain size also took me multiple tries to figure out.
