Great game! The visual style, dialogue choices, & narrative is really well done. I really liked the diner section of the game. The inclusion of sound would greatly enhance this game.
There is sound! Was your browser muted, maybe? You can listen to the songs for each level through the "music" button from the main menu/settings link (so you don't have to replay, if you wanted to check out the sound on its own).
I was playing in the Itch.io Desktop Application. The sound isn't work on there, but I just checked it in another browser and the I hear the sound now.
