This style is lovely! I am a huge fan of complex themes (like comas or the afterlife) being framed and worked through with a lighthearted aesthetic. I feel that the music adds to this as well. It's pretty relaxing without feeling childish or oddly upbeat for the premise. I think this has the potential to be a really interesting game if you have the time or energy to develop it further! That you focused on getting it this complete rather than overexerting yourself is a great success on it's own. Keep up the awesome work!
