Created a new character althought she is not in the game jam plan. I can feel the character has flaws but I will keep it for now because of schedule.

This character is a preta (hungy ghost). Her motivation is to hijack a limbo train, escape her preta realm and find food. I don't think she will be in the upcoming content, but she surely is designed for the Limbo Express project.
