I've been playing the demo today. Advices:
1- Try to create the raptors close to the floor because they are falling from the sky.
2- Try to make the muzzle flash of the gun no so transparent and try to create a yellow light every time the muzzle flash appear.
3- The animation of the raptors looks good in MED but during the game play they look like robots. Try to use the blend function to make then smooth.
4- Work Hard in the graphic and the illumination.

So far so good. Keep Working Hard. Good job.
