Okay, i just thought of this, what if the User [YOU] don't move the ball, what if the arrow keys don't make the ball move? sounds crazy eh? but think about this, the game is AVOIDNESS, avoiding stuff is like, the main thing, but if you can just move your ball back and forth, even with obstacles, it'll be too easy, so get this, what if the arrow keys tilt the whole stage, you build a few ramps, some simple slope detection, and add a few power ups and boom, you got an A grade game, think about it. you press the right key and the stage tilts that way, you press the left, and it tilts towards the left, you press space, and the whole stage moves downward, kinda like a jump. just some, you know, advice.
