Gravity Pinball 2
Gravity Pinball 2 has you manipulating a pinball with your mouse. Once the pinball hits a wall or any solid object, it disappears and you must try again. Some blocks will be moving, others will be invisible and some are vanishing! There are also evil spheres - these are red and must be avoided at all costs. You'll have to start on the Very Easy level in order to unlock Easy, Medium, Hard, and Very Hard. It even has a level editor so you can create your own stages. Once you get the hang of the mouse and keeping the ball in the air, you'll enjoy working your way level through level, seeking new challenges and unlocking harder difficulties.
