Very cool track. Another main contender for the prize! In my opinion it fits the theme. Great production quality.

Nice underground/underwater vibes!

Really nice vibe! Love all the little production stuff, like the echo's and reverbs that give a feel of a big space.

Very cool vibes, perfect for the theme, this is one of the best in the jam!

Credibility took one star of hit but everything else got 5 stars because this is a knockout.  Of the ones i reviewed so far its tone one that -gripped- me immediately the most with atmospherics.  The melody-slides at the beginning were perfeect.  Echoing gives the cavern feel.  Again almost all of us get credibility a little less because 1985 SMB is soo low-tech that accurately we would make some bare bones chip tune.  But this submission here is perfect for like Super Metroid era (1994) or newer remake of the game.

Out side of itch if you posted this on Soundcloud all the repost exchange general-use musicians would rate it easily 9.2 or higher out of ten on the first campaign you burned credits for.

Felt really sharp.  Good job.

If you do rate my project back the correct links are out here:

because I messed up and got caught submitting accidentally the last project by not moving the default settings.

Nice sounds, and "deep" feeling to the track, fits well with the theme. Lacks a bit of melodic elements to me, but this is well crafted and very pleasant to listen to, nice job !

Ooh those chords. Also love the rhythm the chords are delivered in. Very well done percussion, nice panning all around. This paints a great cave/underground atmosphere. Nice work! 

This was very good, I think you did a really good job!! All i would have liked is maybe some slight change in the timbre of that ascending part that loops over and over to give it some slight differentiation throughout the piece, but this was reallly really good, nailed the more calm but slightly creepy vibes!!! Excellent work as always :>

Super nice to listen to, great vibe, we can definitely feel inside a cave/underground, well done.

although it doesnt feel official, the song feels like a official ost from a fan like game that is heavly inspered by mario. also the intro/start SLAPS! great job
