Information channel:
What was those swelling synths in the beginning? Those really caught my attention, but I felt it grew tiring after some time. Try removing it near halfway of the piece. Love the percussions that come in at 1:30 or so. Also, when you restate the theme at 1:57, I felt that you should change the backing tracks a little instead of still sticking to the swelling synths, as to provide some variation to the piece. Or is that a loop like Marius stated?
As for the ending, most game music that loop end by fading out. You should try it too. 10~ 20 seconds of fading out would suffice.
Good piece overall, looking forward to hear more.
