Quoted from CrazyLevi:

The game is universally loved here as is so I wouldn't expect anything anytime soon. Coders all moving on to other projects.

Quoted from silver_spinner:

it needs a ton:
voice call outs galore (from the kids esp), a redemption option in the menu, an option to display "card reader" on attract mode screen and 1 swipe per play (like jersey jack). hitting demogrogon to score points when it makes noises (not just points from hitting inside hole)., a ball saver from hitting center targets when ball drains down center (turn on or off or timed like gene simmons kiss or groot kickout),.
needs a timeout for center ramp staying down when in demogorgon mode so if you cant hit the shot in the mouth the ramp is not down for the entire ball getting in the way. or, make it if you try to hit it 10 times or so (changed in menu for number of shots) and it recognizes you are hitting balls around the mouth, just give the the shot collect.
Also , a use for the action button on lock down bar, maybe a smart bomb to clear the demogorgon if you cant hit the shot which is near impossible on most machines?

Quoted from Richthofen:

Same reason the GEM shot is so tough. It’s a really challenging shot among a layout of makeable solid shots . When you hit it you feel like a hero.
