I like what you've got going here, but a few tips from me (note that I write this without the context of the game you've written this for):
The composition, especially in terms of the chords, is pretty random. I don't know if that was the intention, or not, but I could;dn't find much direction in it. Maybe study some music theory to help yourself keep it a bit more cohesive. I'd be willing to help you out if you like.
It's also pretty empty. The piece lacks bass and sub bass frequencies, which kinda leave this piece without a foundation.
The periods of silence you have after the climaxes are pretty jarring, and don't really help the flow of the piece.
That said, I can tell that you've got ideas and potential. As I mentioned earlier, I'd be more than willing to help you out a bit, if you'd like. Fell free to just message me questions, and I'll do my best to answer! I look forward to what you'll be making in the future
