Games are tailored like the script of a theater play.
I used to compose this play as a three acts.
#Act 1:
traveling
#Act 2:
surviving/fighting
#Act 3:
eating
so, this is the script:
You are a vampire, you have to sleep during the day while traveling in your train because your enemies forced you to keep moving.
When you wake up each day you have 10seconds before you get burned , to avoid the sun damage find shadows and something to eat which can increase your lifetime
