This is a tricky and challenging puzzler-skill game. Your objective is to get to the exit. You do this by jumping on and around platforms, rotating the screen and by shifting from the foreground to the background and back again. You can shift between fore and backgrounds at any time (while moving or not.) You can only shift if there is an empty spot available, otherwise you will remain in the layer you currently find yourself. Shifting and rotating are key components of this game and you must learn to use them effectively if you want to solve the puzzles. Also, take note of the angle of the lines on the outside of the shifting area - that will tell you the direction of shifting your avatar will take as you move between layers. Goodluck!
