This game is kind of an insider tip, it is not well known, but can be very addictive/frustrating. The goal is to hit balls with your ball that is on a pendulum string, the catch is that if you stretch the string too far it rips off and the game is over and the more close to ripping off your string is the more score you get and this is all multiplied by the combo you do, so the more risky you play the more score you get, exponentially more score. There are also power ups that make your string longer and your ball bigger which helps you to make even more scores, but you have to be careful if you stretch your string too much it becomes shorter and it may become unplayable if the string is too short. Additionally the screen will start to move in various ways the longer you play. So the longer and better you play the higher the risk and reward gets, but when you fuck up, it is all over. What motivated me most was to show off my score to others, I don't know my highscore, but I think I had like 250+ combo and all the numbers on the scoreboard were filled with numbers.
Worth trying out, especially since it is free.
