I think I hear 3xosc somewhere in there. Haha. I love 3xosc, it's so useful.
After just finishing a more melancholy (according to one of my friends) song myself, I'm in a pretty good state to listen over this. First, I'm a huge fan of simple waveform synths. They sound retro and common without being boring.
As far as this song goes, I'm giving it 4/5 because it's very promising and has a nice mood to it. The drums have little to no sustain though, which makes the ending stretch a bit jarring when juxtaposed with the previous bit. Also, it ends much too soon. That having been said, I see it's a remake, and for a remake it is very good.
