Stay in the shadows.
You are a shadow person and will burn if the sun touches you.
The player will use arrow keys to move the shadow person on screen around. The sun will slowly move so the player will need to constantly adjust their position to stay in the shadows. To win the player must run to the goal. The shadow person has a health bar and loses a certain amount of health every time it touches the sun. The player loses when all the health is depleted.
