I just setup Munsters on location, and here is my feedback so far on v0.91:
My location is a dark bar, as I’m sure many locations are, and some of the lighting effects on Munsters make it impossible to track the ball.
In particular, after hitting Spot during the mode, the playfield goes dark momentarily and you cannot track the ball whatsoever.
There are also some Jackpot animations where the lights sweep and again you cannot track the ball at all without lots of ambient lighting in the room, something many locations will not have.
Perhaps a setting to disable the most intense lighting effects would do the job.
As it is now, people are starting to time out the Spot mode because hitting the target and not being able to see the ball return is instant death and extremely frustrating.
