Lighting modes needs an easier way to happen. The current method of hitting the Ghost target, slime, and hitting Slimer seems like a great way to get into a simple2-ball MB. Here’s what I would do:
Progress carries ball to ball. Spell GHOST to get slimed, which lights 3 random shots green. Collect those and Slimer drops. Hit him to start the MB. In the MB you have one green shot light. Collect that and Slimer drops. Hit him to collect the Slimer jackpot. Next round two green inserts. Continue in and on. After the second or third round, add-a-ball lights.
To light modes, I don’t know. Make the player hit all three mode shots and then they start to pulse to start the next one you hit.
