I'm enjoying the first half of the track. The playful introduction of the melody and development with some polyphony is great, as well as the variation starting around 0:51. Also, the melodies leave enough space to breathe so the chiptune sound does not tire the ears.
In the second half, it feels to me like the track does not really know where it wants to go. At 1:10 we are thrown back to the beginning (kind of unexpectedly for me, because of the buildup before), then the kick gets introduced to punch forward, but the melodic instruments do not drive the track forward.
So my suggestion would be to rethink the arrangement of the second half and combine some ideas of the first half (like the polyphonic melody and the arpeggiated driving chords) with some new ones, like the shift in tonality that happens at 1:35.
