Really nice ambient orchestral work that I think perfectly suits the sort of game you describe.
nightfall by the coast:
Like the big quartal string swells under the sparse piano line. Plays nicely with the ambient sounds and does a great job setting the mood.
wandering by moonlight:
Mischievous-sounding. Gives me Pikmin vibes a bit. Short and sweet.
as the fireflies bumble past:
Still nice, but I'd say the weakest of the bunch. I like the way the different textures play against each other, and I think the main riff is cool, but the rhythm is so strong and goes on so long that the one little section of piano melody kind of gets swallowed up, and the absence of variation makes the piece as a whole feel like it wants somewhere else to go.
contemplations and quiet revelations:
Loving the bit after piano drops out. You create a nice sense of tension and progression here from the interplay of so few parts.
suddenly, dawn:
And we're back! Recontextualizing the piano melody from the opening, and the unresolved ending, really help tell the story.
Awesome job!
