I like it at first, but it gor boring and forgetful real quick.
It's the repetition, i hear no variety or change, and the little instrument changes and adds you do, end up being repeated also!
I did like the Caribbean feel of the drums and it has this great energy that fits perfectly on a platformer.
some variety would make this better, on the drums, or the instruments you use, or the note progression of the line. or u can just shorten it a minute or two.
mixing seems okay, drums are too much in the foreground, and overall, it's nice to listen to.
