Alrighty, not familiar with the source/game, but you posted it so all is well. Let's see what you got, shall we?
I like the idea... I don't think I'd ever imagine writing an electronic/dance version of this song. The source is strong in your track (perhaps a touch too much so, for OCR), so while it loses it's tribal feel it still sounds like the source. It's just a bit more... upbeat.
Hmm... that beginning wasn't grabbing my attention. 'Tis a shame, since the sidechaining part had some nice bite to it. I suggest starting with the sidechaining and bring out the theme so it isn't drown as much. That'll get our attention better
This is pretty sparse. I notice a lot happening, but none of it fills the space. Use some texture in there that'll fill the soundscape better (pads, short electronic textures, whatever works).
There's a note that doesn't ring right with me at 0:46... I think it's the melody note, but I'm not sure. Fix em'.
Drums... well, you really could use a snare . Hats would also help. Just because it's four on the floor doesn't mean that you need a boring drum - spice it up with some little tasty hat work, and finish it up with some snare SPICE!!
Yeah, it really needs something... more, in there. I'd love to dance to this, but there isn't enough sound to really get me going, here (I'm picky, like that). Ah well, keep it up, right?
