Ooh this is really cute!!! idk how this doesn't have way more favorites yet. All the playing/singing is really great and I love the guitar tone. Something about the chill rhythm and guitar line reminds me of the Toad Harbor music in Mario Kart 8 (which is a high compliment I love that track). and the way the spacey guitar joins in at 2:59 when you say "space between" is so perfect. I don't think I'll ever get tired of hearing gameboy with live instruments.
In conclusion: super lovely entry; I'm certainly going to be listening to this a lot :)
