Just draw lines with the colors,to switch between them click on the squares at the bottom. Blue-The monkey can walk and jump on it. Red-If the monkey touches red it will die and go back to the beginning of the level. Yellow-The monkey will go to the next level.
If there is a glitch please comment below and sorry if there is I will try fixing them. If you make your own level and want other people to play it then remix it as the background of the game.
