Only thing that bothers me with When Pigs Fly is that the hit detection is a bit off. You already die when you are literally right next to the obstacle (ie the pixels are right next to each other) and also it seems as if those stalactites are only one big block. So the stalactite that sticks out most is the hitpoint for the whole obstacle. So it looks like you don't even hit the obstacle but yet you die.
Other than that it's a funny game. And when I find I can't beat one screen I move the game in the background, do something else for a while and then try it again. This often helps to calm down and then try it again without being too angry. :)
