Hey velopman, thanks for playing the game! I was the composer and sound designer, and your description of "spooky but not too spooky" is the exact vibe the programmers asked me for :D I love those playful, cartoonish alien noises
If you're interested you can see other games/audiovisual projects I've worked on here: https://vimeo.com/user132445511 (or on my itch.io!)
All the best
