Kristal

You have been transported to a strange world where you must negotiate a series of platforms while dodging four enemies – a giant insect, a fireball, an axe and a snowman. Yes, it really is a strange world! The platforms contain lots of identical objects which you must get rid of. Touching one of the objects throws it off the platform; hitting one of the enemies with it scores bonus points. At the top of the screen is a blue crystal, and once you’ve collected all the objects, it glows red and you must stand below it to go to the next level.
