Your music fits the theme better than any other I've heard so far. The brittle -sounding synth evokes the glacier, and that thick bass synth makes for a boppin' version of Hell. Thanks for giving us an example of exactly how this might sound during gameplay.
Using chords in the bass register tends to muddy up the mix, though. Maybe just use octaves, or move some of those voices into the midrange; right now it's all highs and lows.
Great work overall!
