You are both stuck in a death game and now you are tasked with a mission. Complete the game! It should be easy right?

You are on the same class as Ichika when suddenly a daruma doll popped off your teachers head and now it tasked the whole class with a game of red light green light! to win you only need push the button behind him and you beat him! The only problem? Your head turns into a bloody puddle of marbles if he sees you move. Good Luck..
