I would love to help out with audio for the game. I grew up on it as a child (it's actually what got me interested in music!) I've done radio work in the past, both as a voice actress as well as an audio editor (and a copywriter, though I would imagine that's all sorted out already). Please let me know what you need help with and if I can be of any assistance!
I would love to beta test for you. I'm particularly good with proof-reading (I'm an editor) and grew up on the Loom game (it's what interested me in music as a child).
