Nice idea that with the player hud, but as you can see, the text in the health bar is a little bit hard to see, and it also looks like the nummer 1 in "100" on the health bar is getting a little bit cutted off.
But i liked how it looked, just get the color thing fixed
Edit: Hmm its seems to look a little bit better on the screenshot than what it dose ingame, wierd...
Edit2: An idea, what about making the background of the health bar Red, and the background on the F1,F2 and so on, Green?
what do you think about that?
Edit3: look at the second screenshot, thinking of how the numbers are counting, its like 567/89 for me when i'am thinking of stuff like that this would be more normal for me 89/567, but thats just me :P
And remember this is some minior thing that i think should be fixed its not something that needs to be done something with, but it may help get the UI perfect? :P
