I like that you made this all out of public materials. I really like using public domain music in my games as well. It's a nice message, and I greatly appreciate that you were willing to make a quiet and low-concept game, which is both daring and tough to execute.
But...you really shouldn't have a branch of your game that scolds the player for not choosing the option you wanted. Just take away the "don't go in" option so they have to, or end the game with something like "You walk away, wistfully wondering what you might have missed."
