Hey - I think this is an interesting concept for a game - particularly if you're trying to share a message about dealing with depression or about happiness in general!
I noticed as I played that the soicalize button didnt seem to do anything when I pressed it though? The rest of the game seemed to function fine, though I wasn;t sure where it's leading to - maybe you could interweve some narrative about moving from hopelessness to hopefulness as the game progresses?
