I think in the ice areas is would be more convincing if it was hard for your character to run on the ice. There should also be some slipping and sliding. And i think you should be able to slide faster and further on the ice than other areas.
That also makes me think that sliding and landing on dirt should create a lot of dust. And landing on ice from up high should make it crack. Just saying.
#Ice is Slippery
