Hearing Ghost Island from PAC MAN just makes me think of “Go Vacation” for the Nintendo Wii. That game has a FANTASTIC OST if you haven’t heard it before. They even ported it to the switch. It includes many tropical as well as various jazz arrangements of lesser known Bandai Namco songs.
Whenever I want to feel good, I listen to the Beach theme from Plok. The game already has one of my favorite soundtracks ever, but there's something so uplifting about that song in particular.
