There is one error I encountered: in the 9th board I purchased all board widener/hightener but the balls now hit an invisible wall to the right and can not reach the most outer buckets.

Thanks, I reproduced the error. It looks like on board 9 if you get the taller and wider then you can fully score all the way to the left buckets but there does appear to be an invisible wall on the right edge where the original was. If the balls get fast enough they can teleports through but in general cannot score on the right 1/4 of the board. I'll get a fix out shortly.
