You are a white dot and you're in a swamp.
Those black circles are stones and since you can jump, you don't have to drown yourself to reach your goal, another stone.
Those stones are quite a distance apart from each other so you'll have to use those green things to bridge the distance.
But, white dot, this swamp is forbidden territory ! You can't leave a trace.
And that's where it becomes difficult, you see, when you reach a stone, all those green blubbery things around it go up if they were down and go down if they were up.
Surely the swamp masters will detect any change so be certain to leave the swamp in it's original state or you will be a red dot !!
