Make it through each level to win! In Lost fluid, you are a droplet of water. You must travel through a system of pipes and figure out how to solve each level. You will need to turn on lights in a certain pattern, collect things, and backtrack to figure everything out. Use the directional arrows on your keyboard to move. The up arrow is used to jump. The left and right arrows are used to move left and right. Figure out how to reach the end to win the game. If you get stuck, you can push the hint button to help you out. Good luck!
