Aftermath puts out a lot of the music I like. They're one of my main influences I'd say. I like aggressive music, as such I will (try to) produce aggressive music.
So I'm not sure how it sounds like videogame music. My guess is it's because all the beat consists of is a Harpsichord and mono drums, and not much else. If I added more conventional instruments it might sound more like what I intended to make I guess. I've also had one of my sister's friends who is a game designer compare this specific track to castlevania before too.
