There's a lot of charm being put into this for a low stakes Gameboy game, you really nailed the atmosphere of the calm and mellow atmosphere with the chiptune.
I also like you added an orchestral piece for a promotional bit like in old videogames, which I don't see that happen in the JAM
The fact that you used Musescore to make it also surprises me, I didn't know it can be used for making this kind of purpose, great job.
