Plain Bouncing Marbles uses a simple bounce physics system where holding makes the marble rise. i find the touch and hold control is the only button you need.
Touch the screen to make your marble bounce upwards, holding longer makes it bounce higher.
Controls are touch and hold. The game is an endless jumper style with random platforms and coin collection.
Most players must time holds to avoid edges and obstacles that appear randomly on the path. It is better to time your holds so you bounce just enough to avoid the edges.
