I've reviewed one of your tracks (upon request)
Both Nightmare calamity and Nightmare Collision, seem to remind me of different stages of Mortal Kombat Games.
For instance, the first one. It really reminds me of Mortal Kombat: Mythologies - Sub-Zero. The creepiness of entering a temple, that you really shouldn't be at. Where as this, Reminds me of Mortal Kombat: Armageddon - Of the side game - Motor Kombat. It's like a Darker version of Mario Kart, but allot of the music on it was Drum n Bass like (like this).
Never the less, I'll carry on with the review.
The beat was on time (you're prolly thinking so what, big deal) but in my time, I have heard some pretty woeful submissions. Where a normally beat for them, was the hard part. Notes, used wonderfully well. Atmosphere, very good
And overall feel of the piece
Very Good - Well done
