Hello, the theme is sort of a guideline to inspire you, you are free to explore it the way you like. There's no rating for this jam and no winner.
I would however say, if you think you have a good idea for a Bitsy game, it would be better for you to make it outside of the jam, because you might feel constrained by the theme, or the deadline. You can do another game if the theme inspire you, but whatever you decide I would be happy to see your submission :)
