Hurray!!!! An adventure game with a female character! Finally some one is taking us tomboys seriously! Wait... Was it a tomboy a girl who likes boyish things or was it tomgirl or somthing like that... I don't know. But who cares!
The chill spell should be able to freeze enemies, and maybe after getting a spell that is a upgraded version of chill that replaces the first one, be able to freeze those moving cubes that you can't kill, and after one more, make frozen blocks in the air to make stairs or something to help you reach higher places (the blocks can melt by the way so you don't accidentally block off a path). Think about it.
I think that the chill spell should be able to freeze enemies and maybe after finding a added upgrade chill spell somewhere later in the game be able to freeze those annoying cubes that move around that can't be killed, and after another upgrade be able make ice blocks in the air to help you reach higher areas. Think about it. Where's the minimap that everyone is talking about by the way?
