you have mastered the little green square. to move, here are the commands: up arrow: jump right arrow: go right left arrow: go left you can pass through the obstacles in black if you enter them horizontally. this will allow you to jump higher (I don't know if you understood) the small green mushrooms are trampolines. don't touch anything red or you will die. the blue circles are portals that teleport you to the other blue circle. ALL levels are possible. some of these levels require a little thought. good luck ! (I am French and I wrote this with google translate so there may be some errors)
