Plok

Plok is a side-scrolling platform game. Plok can launch any of his limbs at will to damage enemies. Once the damage has been done they return to Plok. Some puzzles involve having to "sacrifice" one of Plok's limbs to activate switches (thus gradually decreasing Plok's mobility and his chances in battle). Once a limb hits a switch, it is placed on a hanger that may be right next to the switch or several screens away; some switches also require certain limbs. (wikipedia.org)
