The goal of the game is to slide under the blocks hurtling toward you. You do this by pressing the 1, 2, 3, or 4 key depending on who needs to slide.1 = top, 2 = next to top, 3 = next to bottom, 4 = bottom. When you hit the green flag, you see a mode menu. Select either Easy, Medium, or hard. Then just play!
