This is one catchy tune! I like the softness of this track -- the piano is on point, the bass line is groovy, and those string staccatos towards the middle of the song really accentuate the melody. The beginning reminded me a little of a Plants vs. Zombies track, but as it goes on, the melody in particular reminded of more upbeat RPG songs. What inspired you to write this song anyway? :)
The overall pacing of the song is great, and you build and deconstruct each instrument well. The kick comes in at just the right time, as does the bass. Speaking of the bass, I did notice that it sticks out in the mix quite a bit more than any other instrument. As a result, you can hear that great bass line well, but it overshadows everything else -- especially the piano, the main instrument of the track. This hampers the melody! Now, all that being said, the bass doesn't stick out like a sore thumb, and every instrument can be heard just fine. Perhaps you could try turning the bass down just a tad.
I really enjoyed the addition of the choir, by the way. The choir adds a nice touch of extra softness to the song as a whole, so you get that feeling of peace. I have to say, at least one more time, that you really know how to build a track. Well done! :)
