I can't tell excatly what is wrong with this.
But that arp, or fast moving synth, whatever it is, is way to fast, either that or off beat. There is defiantly a lot going on at once, which makes it hard to tell.
On top of there being a lot on top each other, it is mix terrible, and a lot of the synths sound the same, and occupied the same frequency. The drums were extremely repetitive and barley any change was in there. The main melody was also played quite often and became irritating. Some of the sounds just sounded way to 8 bit and didn't sound good at all or blend .There was also a lack of instrument that occupied that lower frequencies which made it sound unbalanced.
None the less, it was decent, the breaks where enjoyable. There is potential, and I have heard some real great stuff from you.
