I like your drums, they have sufficient force. But everything else is too much in the background except the sub. The nintendo style sound could define it a lot more if you bring it to the front and play with it a bit more (though its hissing like a snake there, you should try to find another sample of it). Reminds me of super mario. You got the wobble idea but maybe play with the bass more and make more surprising fills here and there to keep it interesting.
Keep at it man.
