It's not bad at all.
First off, Generally, Video Game songs are loops, or have a new track cut them off. This isn't the case in this song, because it fades out instead of an abrupt ending. Just a suggestion, not saying I haven't seen fantastic songs fade out but yeah, it is just a suggestion.
Secondly, I could tell that the bass and the drums were a continuous loop which kind of annoyed me, nevertheless it could be changed to a longer loop with more variation and be a little more pleasing. :D
Thirdly, In the beginning, this is just my opinion, after it kicks off, the note starts a little to low. What can be done to improve it is after the very biginning, you could have the notes a tad louder and a bit higher-pitched like the notes in the middle of the song.
Lastly, When I hear this song, I think of Castle Crashers, if you haven't seen or played it it's an... action game you fight people in :D, but yeah, if this song was in there I would be disappointed because there's hardly any action in this. It's just the same thing over and over with a little different notes here and there.
P.S. The background bass guitar or w/e the hell it's called, shouldn't be the same notes over and over.
4/5 for being Video Game Song and I don't know what game it would be for.
7/10 for the 5 reasons stated above.
thank you for helping me. I'll sertenly reflect over your suggestions the next time I try to make game music =D
I appriciate it a lot ;)
