There's nothing to apologize about. As far as experimental games go, this one isn't bad. There are no technical problems, it runs smooth, it looks good, it sounds good it is visually appealing, it's just the gameplay that needs some tinkering. It's not clear to me if I should try to keep the ball rolling or falling/flying, should I keep it moving fast or slow, should I avoid or try to hit the top or bottom? The black walls seem to pop up unexpectedly and recovering from getting stopped is very hard.
