In Blopper you’ll have to pop as much balloons as possible with your darths. Throw the darts in the air and let them pop the balloons, smaller balloons give more points. There are 3 types of bonus-balloons, which will give you time, extra darths or extra speed.

To advance in levels, a minimum score is set per level, if you don’t reach that score, you’ll lose a life. You start with 3 lives. Use arrow keys LEFT and RIGHT to rotate the darth.
Press SPACE to throw the darth. Hold space longer to throw it harder. Try to score as many points as possible within the timelimit.

To be able to go to the next level you’ll have to get AT LEAST the needed amount of points for that level. There are 5 different point-balloons: 10, 20, 30, 40 and 50 points. And 3 different bonus-balloons, speed, time and multiple darths.
