That's great DarkInferno
Lot lot of good ideas ans stuff.

Now my taste and preferences :
-Bigger hand ? (two hands also ?)
-More animated hands when running/walking ?
-It's a demo but why not improve : animated and visible powers : i don't mean Skyrim like , but more Visual attractive and visible, more on screen.
-Hands moving with fists like when you run , you don't shoot at same time ? Or can only use powers when walking or strafing ?
- Normal map shader ? it will bring a lot in visual and seems really good for that type of game not so demanding on polygons ?

I like the concept of defend game , the powers and the world.

Keep it up !
