Well, this tables, me finger in the air guessing, Are slow and bouncy. Only way to have some control. You have to use your nudge skills. Flippers are still overpowered, yes. And the slingshots at the bottom might be too. But it's hard to find a balance not to get them to constantly shoot the kickers or bouncing from on to the other (chronic FP problem but the ZED flippers with EMKickers are not the solution here I think)
Also, it's my perception, that you have to nudge as part of the gameplay so you can keep the ball moving sideways and not falling. Maybe reducing the slope to 5... It's a hard weird table and there's a b&w old movie but the girl's not even playing and if it was you couldn't see anything. The table is near flat hence my 5º slope comment.
I tend to do the same "move" with the bottom flipper :D
In any case, this is not a release, yet. I just wanted to show you that's is done. Now it needs polishing but without comparison videos - bad YT videos are still better than none - and for such an old table it's just best guesses on my part.
