Short, repetitive, not really useful for anything.
Doesn't have much feeling, as the other review says, it's Half Life esque, but there isn't really much here. Melody is the same, the weird string synth isn't even a melody but still repeats, this isn't long enough to be used for anything. It doesn't even loop right. I'd suggest making the loop longer, adding more changes, and making it loop properly.
However there is some good mixing here, doesn't distort, and some nice stereo sound.
Small critique on the percussion though, it's just kind of generic, I could swear I've heard that same clap in like a hundred different songs, it gets grating.
Overall, not very good, mixing is good, but what's here is just kind of nothingness, I'll check your other music but this song is basically a nothing song.
