I find that in the game, it's almost impossible to get away with it when Jason catches us if we don't have a Swiss army knife on us.
Even with Tommy Jarvis, I never get away with it! (or I didn't really understand how the game works: (
Every time I animate the animation of the murder, I think a QTE would be really good to give us the chance to get out of it anyway, even if it's like "you miss once it's over " X)
The QTE may be more difficult depending on the fear, endurance or strength of the counselor and/or Jason's fury.
Ps: Sorry for my English, i'm French ! ^^
