After listening to a string of rather uninspired audio submissions also labeled as "video game music", this was definitely a welcomed treat.
It's far more original than most, and uses less traditional tropes. I like the chord progression and the instrument's choice.
I feel that the intro is too long, and that the whole thing could benefit a lot from being more compact, it would have a better pacing, a better dynamic. Also, the drum beat is simple, and it works, but it sounds too disco, too techno, it's too punchy for this track... I'd suggest making it more light, and adding a bit of variation in the snare's rhythmic pattern. Mix it up a bit, add of bit of variation.
Anyway, it's a good track, and it shows a keen ear.
