Later we decided to use an avatar displaying how our Joan feels, like you know from where.
In addition to health level it shows whether Joan is using a power up or ability, ammo levels and cool down times for both the primary and the secondary weapon shots.
On the animated pic below Joan starts fully healthy, takes the Bloodlust power up and then receives some damage until she dies, occasionally.
I really hope you like it as mush as we do

And here also comes the full avatar map with all health levels and power ups.
