I saw your post on discord a while back so I saved this to my bookmarks and planned to check it out later. I almost forgot to do so but I'm glad I didn't! This is a really solid submission with such a nice and peaceful atmosphere! Definitely reminds me of an underwater theme from a game like Mario, you did a great job on this one! You did so much while only taking a minimalist approach to the instruments which is pretty impressive in it of itself.
Overall some really impressive work and although you only used a few instruments, you were still able to create such a peaceful and atmospheric track, nicely done! I'm glad this was the track I decided to end my submission reviewing for today.
That's all I have to say really, have a great day :D
