Space Ball Blaster
In the recent past, the planet was destroyed by a marauding race of aliens, before you could even muster enough defenses to protect yourselves. You now have learned your lesson, and have created a space outpost, where you can engage any alien race that may be on its way to attack the Earth. You are on high alert every day, and the soldiers sleep in shifts to make sure that the monitoring systems are effectively manned. Today, you receive confirmation about a string of funny balls moving towards the planet. You study the balls, and finally see how you can make a weapon against them. The only way to stop these creatures is to shoot oppositely charged balls at them, but they should have the same color. When you make a set of three or more of these balls, they are removed from the advancing column of balls. You have to make sure that they do not get to the end of the path or else you will have failed. The secret here is to act fast and shoot down the balls quickly; this may need you to come up with some strategies to enable you to get special features and also combo scores. Combo scores are the life-line of these games, and the more balls you remove, the faster you complete the level, earning you more bonus points for the space that the balls were yet to cover to get to the end of the path. Special features include slowing down the advance of the balls, getting an accuracy indicator, increasing the rate at which you can shoot, and so much more. You can change the colors of the balls that you shoot by hitting the spacebar; once you do so, you get the ball that would have come next and this can only happen once for each shot.
