The game is interesting but REALLY frustrating. You have a music piece (a total of 10 songs which were popular in the 80s), little balls start to fall on board and you need to click on them in time in accordance with the beat of the song. You have levels and each has a number of achievements that you need to get on this level. 2 will be the score achievements (Rad and SuperRad), the others are to either score groups of some special items or to survive 20, 50 or 200 beats without any misclicks. 10 hardest levels with an achievement 200 without misclicks is the point when it gets REALLY frustrating. I tried playing this game many times but I have failed to gain this one. First time I played I spent really a lot of time on this game but did not manage to make it on 2 levels out of 10. Now I am replaying this game and I got only 5 out of 10. I keep on trying and several minutes later I feel like I am close to crush my monitor in frustration so I switch the game off. The game has a really nice and interesting concept and beautiful, colorful graphics, but it gets so hard by the end that you just stop having fun. I am setting the Level of Challenge to "Awful" as it is just WAY too hard. I would not recommend the game if you are as easily subject to frustration as I am.
