Nice work! Fun concept and simple/straightforward gameplay. I would have liked to see more possibilities (I saw the same characters when replaying a few times to see if I'd get anything else), but it's a 48-hour game jam and the graphics and sound are pretty strong.
This would be an interesting game to play for a longer/more complex storyline as well. (Edit: I see you're already pondering that from the other comments. Cool!) Music and setting is pretty soothing.
