Couple changes I'd make to the UI:
- That font is hard to read, it's too thin and twisty
- I'm assuming "out cold" means the character is temporarily unuseable, in which case you should darken or grey out his portrait
- All HP bars should be the same color. Idk what the enemy bar and the red bar on the player's bit of the UI mean, but I'd make HP red or green, MP blue and some other color for the other stuff.
- The gold should be in the same font as the other labels, or at least a similar looking font. It's kinda distracting right now.
The overall idea is good, you want UI that doesn't get in the way of the screen for an action game, and you definitely have that part right. Just need some tweaks to make it easier to look at.
