Quoted from PINQUEST:*the mouth shot. Should it have more or less pitch to successfully hit?
@dg_amuse posted a fix for the demogorgon shot at https://pinside.com/pinball/forum/topic/stern-stranger-things/page/68#post-5385952
I can vouch for this fix as prior it was impossible (<5%) to hit on purpose and now it is very doable (>75%). Made the game feel much more compelling and rewarding (versus feeling like you were being cheated and getting frustrated).
