Blue Fantasy is giving me Animal Crossing museum vibes, which is working for the concept well!
Guidance has some really nice piano lines in it. The repetitions feel good the whole time and that's hard to do.
Fun In Coral Town! is my favorite of the 5. Makes me think a bit of Adventure Time. The sliding melody is great.
Abyssal Nightmare is strangely refreshing because of the change in tone, even though it's dark. I think the bass line really holds everything together nicely.
In Loving Memory loved the repeating intro the turns into a longer melody. Great development with that.
Overall excellent job! Loved the concept and I think a game would work well with music like this.
