Your main menu's play button is the only one that does anything. Settings and credits show empty menus, and exit does not quit the app. If I were you I would just get rid of those buttons... Also the drawn-out fade between scenes kills me...anyway, the idea is not bad. Shoot yourself across the room in a social setting while trying not to bump into people, and it's programmed pretty well. Your tilemaps are pretty creative too. The game, simple as it is, was pretty enjoyable. Nice job!
