I appreciate the thorough review!
Can't believe i missed adding space in the description, whoops! I definitely should change the keys so they are together too.
I love that you got the levels were meant to learn progression. Level 1 for movement, level 2 for Gust, Level 3 for Sun.
The Sleet spell was meant for a (not implemented) "Tough" enemy that could not be pushed with Gust, and would have to be tricked into sliding into Spikes to defeat. (It also has second optional use as a speed running tactic by sliding over your own ice. :))
