After putting about 400 games on mine now, I have a couple of spots that to me would add nicely to this game. The game is a blast to play for sure but, there are a couple of spots that bug me.
The cannon modes. cannon fodder, cannon chaos, cannon volley. Getting these lit pretty much just gives you the points for the cannon shot, there is really nothing to make you care about which one it lit, this could be so much more. To me they should be made to give an award or start something new as it goes up a level. I'm thinking the first awards a bonus, the second a hurry up, and the third a cannon multiball that will start a multiball mode where every time you hit the cannon ramp and make the cannon shot (during the multiball) you get a jackpot.
The lower playfield. There needs to be a little more incentive for making the shots, IMO. It could be much more engaging if you were awarded an extra ball or VIP tickets for say making ten loops and three sets of target bank completions.
Otherwise a fantastic game and these two changes would fill in the two holes perfectly to me.
