Okay, sounds great, composition has some potential, nice texture. The mix, the panning is a good idea but maybe not for the whole song, having the piano staccato on the left the whole time its getting a bit tedious. NO BASS, just add some low frequency somewhere in the middle of the song and that would pull up some awesome dynamics and change the feeling a bit especially if you only have one track for the game. Chord progression, well done but try to open some of your chords instead of doing stacked triad chords, open up a little bit like root note, fifth and third you'll see the song will have more space and magically sound a bit better. Good job !
