Soul Shift is a physics-based puzzle game with a unique object-swapping mechanic. Your objective is to remove all of the red shapes from the playing field. This is accomplished by swapping the positions of shapes so that the red ones fall off the stage. In some levels, you will be required to click on removable and explosive items to complete your objective. There is no limit to the number of times you can swap shapes, but you will lose stars if you swap them too many times. Try to get all three stars in all 30 levels; there are five bonus levels that will become playable once you've earned enough stars.
