In this interesting puzzle game, you control a blue balloon that is slowly losing air. (Although I always thought it was a ball of ice that was slowly melting.) You move throught the levels collecting gems; the catch is, as you move you lose air in the balloon, making your balloon smaller to navigate through tighter areas, but if you run out of air the game is over. A neat idea that is well executed with decent EGA graphics, but its a very difficult game.
