To get past his bread attack, just run underneath a ledge when you see him fly up. When the bread falls, it bounces once on the ledge, giving you time to run out of the way.
I love this game, really, I do, but the game became so laggy on level 11, that, even though it should have been a simple level, took me countless times to complete. I give this game a 10/10 for originality, but please, try to make level eleven less computer intensive.
Well whaddaya know, I accidentally threw the plane backwards, and the game crashed. I didn't read the comments until after it happened and I thought it was just my rubbish computer acting up again.
