Idea to give visual hint of overflow.

Great Game, I am having so much fun with it. Thank you.

A quick idea, maybe easy to implement/test.
I use Grim Feast and it says it can overflow. It's easy to see the overflow number above the life bubble.

I was thinking about an additional visual hint, you could add another colour (darker blue) that goes over the Energy shield bar indicating the overflow amount.
It's easier to see than the number sometime.
I think the same can apply to life bubble (darker red) and mana (if mana overflow exists) with another blue.

So for example when you have full ES and 50% overflow, your ES indicator is half blue and half dark blue.

Thanks again for the great game.
