This is a beautiful flash game developed by Voet Cranf.
You, a saltacole (the rarest species of molusk) must work your way through 5 caves. At the start of each level you drop into the cave through a hole, you must find another hole just like it to get out. However, first you have to find and trip the switch that opens the door to that hole.
You can only move by jumping, swimming or rolling. Use the mouse, point on the molusc, then click and drag the mouse in the direction you want to move. If you hole the mouse down, you'll see an arc which will help to guide your movement.
