Nice!!!
What makes this song in for me is the sliding effect that starts to happen around 1:23 and gets more implemented as you go on.
The following is my opinion and is not neccessarily a valid argument for everyone, I hope you don't take offense.
What I really don't like and have never liked is 3x osc arp king with a HP filter (I assume that's what you're using, if I'm wrong I've just made a fool of myself, oh well).
Perhaps the faint scraping of that particular 3x osc would be better if you were to have the insert filter set to LPx2 and taking the Filter cutoff frequency (modX) and its resonance (modX) to about 50 percent of their influence.
You made tetris proud.
P.S
If you really love that song then it is your duty to take a look at this:
