I think delving with character swaps for animation might be a good skill to learn, with this game being an excuse to practice it.
But I do understand if this idea needs to be scoped down or removed altogether.

Well, the challenge is more about drawing and animating the whole scene. Programing which character to show depends mostly in one single variable. However, drawing and animating 10 pictures for each character, will take me months or... years if I hit 50 animations. x.x
But still keeping the idea in the air doesn't hurt just in case I come up with a solution that saves time.
