Everything has been already pointed out in kirkdewinter's review from 2014. The author promised to fix some bugs in the game, but did not care to do it for about 4 years now. So still:
1. The ball can get stucked vertically near the left or right screen border and you cannot do anything about it;
2. You are still likely to lose a life at the very beginning of the level;
3. One oddity in comparison to breakout games: when you miss the ball it should leave the screen and you should restart with a new ball. Instead - no idea why - the ball can just get stucked below your paddle, making you lose all your lives in less than a second.
