The slimer is basically a mini tilt bob with the metal wire used as part of the switch. Ours was fraying a little bit with "hairs" touching the metal ring. Once we clipped those off and tightened the tilt a little bit, all slimer phantom hits went away.
The layout seems pretty cool, but it's still extremely one-dimensional in that everyone plays a multiball once and sees how many ghosts they can get and pray for Mass Hysteria. The luck-boxy aspect is in how powerful the pop awards and tobin's guide can be (light 2x, light 3x, light super, etc.) Doesn't seem to be deterministic in tournament mode for now. Also, if one player gets a decent score on ball one, they can pile on the other players through skill shots which is a little annoying.
Edit: and the scoleri targets staying up during multiball discourage controlled play as they block the two easier shots in the game.
ETA on this? This was just posted to our selfie league...
