Launch by selecting either Steve or Alex as your character. Guide your character through the house using the on-screen buttons. Collect items like wood and flint to make a fire. Keep in mind that only Steve can gather obsidian. Work through puzzles to access new areas of the house. Combine collected items in your inventory to craft tools or keys needed for escape. Steer clear of obstacles that may stop your progress. Cooperate if playing in co-op mode to leverage each character's unique abilities. Get out from the house by creating a fire to alert for help.
