Incredible, but the UI can use some work.

Loved the game on my computer. Love it on my phone. I noticed a bar filling up bow my shop, but I have no idea what it means. At first I though it was something that shows you how close you are to getting another EMP, but the bar seems to exponentially slow its fill rate the fuller it gets. I guess its just for multipliers? If so, I do t get why it cant just fill at a flat rate.
