Exercise 1 - Rube Goldberg Machine

Dark Rescue is a platformer game where you play as a witch looking for her lost cat. The primary mechanic is that the player's light source is limited. On jump the light pool increases but only as long as your jack-o-lantern has enough light energy. Light energy can be gained by "trick-or-treating" (i.e finding orange candy collectibles). Dark energy (collected through purple candies) does not deplete your light energy stores, but it will "disorient" your witch (i.e. reverse direction of controls). Witches hate ghosts, they can "spook" you to death if you let them get too close. Other included mechanics are common platformer standards -- moving platforms, pushable blocks.
