Industrial DnB!
That's what it made me think. You had some pretty interesting machinery-type sounds, like that hissing noise, for example. The drums could have slightly more variety, but it's nothing really tormenting to the overall sound. The main dark theme is awesome, kinda makes me think evil bad guy factory or something. Maybe an all out intense part that's totally full blown would be nice : )
-Well, you did this nicely, and it was quite enjoyable. Well, if any of my songs are "magically" going to get a review, it'll might be TRS-Marimba Mania! Keep in mind, if it's magical, there will be a raised review score and overall score, meaning above a 4. Lol, just kidding with you, do what you want.
-Great job!
