Great cover
I've seen this used in many custom made versions of Mario games usually during castle or space levels. Now that I hear the original it sounds great and the flow of the tune is quite awesome to hear it remixed in such a way as well that it makes people feel awesome and epic for some reason too.
The synths sound incredible here and give you a dismal doom of hope kind of feel too. The drums sound good hear and I really like how they go as well. Like the backing synth being soft and working alongside the bass. Enjoy the effect of how the beat always sounds like it is getting ready to go off which is cool.
Overall, awesome cover!!
