HMP Arena will kill you a few times without using it, yes.
UV Arena will kill you a few more times without using it.

That being said, I agree with Thomas. Currently, most players require the use of the corner trick to go far in the game. And the game isn't that fun to play if you can't win every once in awhile. To be honest, if the standard game was easier, you might even get a few more players, and the Challenges would feel more "fun", as they're making a game that isn't TOO hard to beat up to the level that it is at now. Then again, there are those that simply excel at the game. For them, we can always implement another difficulty level. ;)
