Great chiptune track. Very creative with the limited NES sound selection. Nice!

Awesome beat and fantastic and catchy as hell bass line! Great, rich and full of energy work sticking to the original soundtrack limitations. Good job!

This is some really cool chiptune. Very cool harmonies. Great work!

Very solid track, even if a bit distant from the undeground theme, using the original sounds with all its limitations is a great choice. Well done!

It's a little more upbeat than what I was expecting but it's still a great track! Well done. 

Damn, nice groove !

This sounds incredible for sticking to the limitations that the original OST had. I like the melodic development through the piece, and the rhythm is really satisfying! The entire piece has a very strong sense of forward movement too.

Some parts of the melody and harmony do sound a little bit like sonic music, which detracts a little from the whole underground theme. I think with a little more bass presence this would fit really well.

Overall really great sounding composition, well done!

Yeah this slaps hardd

The music is really very nice. The 8-bit instrumentation is controlled, and you can do a lot with just 4 channels. (The noise is perhaps a little too loud from 1'20). The riff is good and the development interesting.

...but it doesn't sound very Mario ^^'.

it sound more like a undertale song then a mario song. but it salps AF
