First of all, I like the the chords that came in in the beginning. You did a nice job of panning them.
The first main part sounds chaotic but neat. I would suggest not using so much flange/phaser in those synths because it makes the mix less clear.
The high hat in the second half of the song is sort of piercing and annoying. Would've recommended re-equalizing it so that the lower treble is higher.
For the emptier parts, I would recommend filling them up with some extra, but still clean and quiet reverb.
I like how the sounds themselves interact with the melody. It sounds fun. Good work!
