(I'm going to copy-paste this, sorry for anyone reading it twice) It multiplies each ball by the x amount! I apologize for forgetting to write the tooltip.
It's probably a little overly complicated. The way I'm planning the system currently is this:
Drop I - reduce cooldown of manual drop
Drop II - start scaling ball count up for manual drop to help get through the stages faster
Not sure if there will be a III
And then the same system for Auto Drop.
These got added at the 11th hour right before we cut the demo. They're not balanced or clear and I don't like them and I dread them. I will be consulting with another designer to see how best to stretch this game out in the higher levels.
