It's pretty neat actually,
The beginning arp is a good way to start the song for sure. Perhaps try applying a filter or stronger filter to it to give it some variance.
1:20 - The synth popping in now and again adds further flavour to the piece. Very well written.
1:34 - The completes the song in my opinion. It definitely gives it the video game feel. However, at 1:47, the notes are severely out of tune. They're out of tune again at 2:07. And at progressively different parts of the song as well. Whatever notes being used at those times either aren't apart of the scale youre writing in, or they're chorded wrong.
Overall - pretty decent track :) Just gotta work out a few kinks here and there and you'll be good to go. I can definitely picture this in some type of arcade game!
