I'd like my summer back, please.
What kind of person prefers ice and snow, Ice...Penguin.. oh.
Anyway, it's looking good and sparks my imagination: What kind of island might this be? Does it have high mountains with snowy peaks? Does it have different weather zones? Does it feature different seasons (like in Oracles of Seasons)? Is it generally set in a colder region?
On second thought, if climate change has taught us anything: Ice is a actually good thing. And the sliding might make for some interesting puzzles (Chip's Challenge, anyone?).
