It should have less drums and focus more on the "8-bit final boss" effect because for me it sound like you're trying to cover more than one genre at the time and i personally don't really like that.
It's still good though, liked how it twisted itself at 00:28 and 01:45, it's not the best piece i ever heard but it is good and it deserve 5 stars and a vote of 5 from me.
I'm very glad you enjoyed it. And yeah, I'm a really big fan of how in a composition just changing one thing can completely alter the mood of another part. I'm just getting started here, so all this feedback is appreciated.
Please contact me if you would like to use this in a project. We can discuss the details.
