I've never played the game in person but I have watched Dead_Flip's live stream of it, and I was pretty much hooked right then and there.
I think my favorite part of the whole game is how creative the programming is here. The whole "Infected" mode idea, the skill shot, and other features and mechanics are truly unique and make the game stand out. Makes me want to play it or potentially own it someday, but I have no idea when.
Just throwing out some ideas off the top of my head (sorry for being long):
*"Dirty Pool" award: I've seen balls make it past the drop target when it's still up during the streams. Perhaps you can get some kind of animation (maybe a literal/Rob Zombie take on the phrase "Dirty Pool", which I can only imagine how disgusting it could be...), speech/sound and some points. This could also give a free hit to the drop target or instantly light lock, whatever seems more balanced or enjoyable for players.

*Sub wizard mode: I liked the ideas that some people had for this, mirroring Sea of Simulation from Tron. Perhaps the premise could be that, with each mode completed, you progress deeper and deeper beneath Earth's crust on your journey to Hell. If you reach a mode that was incomplete, you'd have to complete some sort of task in order to continue through the ladder of modes. For instance, with Dead City Radio you'll be forced to hit the "1, 2, 3" targets to advance. Don't know what this sub wizard mode could be called, though. "Great American Nightmare"?
Perhaps also if you reach the mode, any incomplete modes will go off and you'd have to collect them again, while completed ones stay on, again like Sea of Simulation? Or there's a special bonus if you manage to complete everything in one go to reach Hell Bound?

*Shot Multipliers: Doubles one shot on the playfield that has an arrow insert in front of it for the rest of the ball. Perhaps this could be lit up by bashing Spauling, completing the top lanes on his upper playfield or some other task?
Additionally, if you collect all the shot multipliers on the same ball, a flashing arrow worth triple scoring could rove across the playfield (like Transformers).

Keep up the great work as always! Congrats on doing such a fantastic job with this game already! Looking forward to playing this game sometime in the future!
