I mostly agree with everything said here about the tight controls and the weird choice of music. About the material too far away, I think I get why, to feel alone and stuff, but the fact that penguins kept flying against my base as soon as I wasn't looking and the general lack of things to do while away made me want to speed up things instead
I'd like to add that the parallax and fog on the terrain are great, the poisonous gas should have come with another damage sound though :) maybe acid or sandstorm ?
