> For those puzzles with the "reverse" tiles that bounce the ball back, I had to turn off my expectations of where the ball is going to go next. In puzzle 5 you send the ball straight out to a reverse tile and my expectation would be for it to just bounce straight back to the entrance tile, but no... it turns left after that. Just a minor complaint.

It's much worse than you make it sound; exactly the same tile layout gets you different results in different places.
