Could you provide titles or descriptions of how you were imagining the songs and SFX would be used?
For now I will call them Song 1,2,3 and SFX 1,2,3
For the music:
I liked your use of trim and phasers and longer effects that go over the whole phrase. Song 3 was exciting, a little bit of a rock thing going on. All together your three songs sound like a very different game. I am imagining a little point and click adventure game where you play as a kid learning about nature and magic. I like them, it is relaxing and pleasant.
SFX: In general, get more sound effects, and layer 3-6 on top of each other
1. I could not hear the first sound effect well enough to figure out what it was maybe someone flipping a pancake in a different room?
2. Rattly bones rattle well, but I think this is three variations on a bone SFX. I think it works even better if you layer them on top of each other.
3. Sounds like an inflatable died.
