After watching the most recent video (the one a few posts above) I can see this being a fun game. Allow me to make a few suggestions:
- Would it be a thought to stick with common (B/W) colors for certain elements? Like green lock targets and inserts, orange insert to indicate Extra Ball, not sure, but aren't jackpot inserts and targets usually red?
- please add more callouts (lots)
- wouldn't it be better is the ball lock callouts would indicate which ball is locked. E,g: "Ball 1 locked" "Ball 2 locked" etc. Maybe even indicate how many locks are needed for MB: "one more for multiball"
- The current music appears to be EDM tracks with 'song' arrangements. For pinball you don't need songs, you need themes. A long buildup to a drop where the beat kicks in will only work if it makes sense in the game.
- Following the previous suggestion: please improve the music choreography with other elements in the game, like lightshows, video, and such.
- Please add shooter grooves, like Scott Danesi did on TNA. These are short looped elements (2 beats or 4 beats) with no bass and once the ball is plunged the regular theme (with bass) kicks in.
- Tie specific themes to specific modes (see also next comment)
- I hear no progress in the game music after draining a ball. I'd assume if you drain and get a new ball, and you continue where you left off. Maybe you do in terms of rules, but as the music changes, that indicates to me that the mode changed.

Hope the above is useful
