Thanks, the little circles are the hexes, if you use the frogs you can light your way above you or get a feeling of where to shoot. If you hit a hex it turns into a platform. Also theres water drops from the top that can hit hexes which is why some will turn into platforms on their own.
If you left click and then drag towards your player it charges your wand, let go of left click and you launch a frog. It send the player flying in the opposite direction. So if you want to go up, point it to the ground and shoot.
