How to play: there is a demo game at the start screen, press the middle button to play the game or control the bomb to hit it's button. To control the bomb, you have to control the player by right and left arrow and also space bar. Then try to move the player to the rotate wing (the green things). I'm Vietnamese so I don't know how to  explain the strange physic but you can find out in the demo version at the start screen right ?
