K, first thing I noticed. This song is really repetitive... And I cannot stress it enough, repetivity is huge when it comes to video game music. However, the tune is quite catchy, and I do like your mix between the 8-bit synth and the bass/drums. And even though the tune is a bit repetitive, I can see this being used in a video game. So, overall I think you did quite well, however I feel you should move a bit more away from that repeating melody.
That was kind of the point of this tune though. It wasn't a verse/chorus concept, but more just a jam that builds and builds. it's really a song to just vibe to.
Please contact me if you would like to use this in a project. We can discuss the details.
