A little to much reverb in areas, the bass I'm thinking. I'm also working on making some 8 bit music myself. I'd work at making it more solid with the sound. Just listen to some 8 bit tunes to help you out more. Unless you're trying out a new 8 bit like sound mix with things. It sounds pretty good.
I've added a reverb because with earphones on I went crazy with beep noises. so....yeah..
Please contact me if you would like to use this in a project. We can discuss the details.
