Sci-Fi Demo (BETA)

I'm a UnityEngine Beginner and this is my 1st attempt in making 3D games, I made a Sci-Fi game BETA with basic moving and shooting dynamics and 3D effects plus i edited the environment with post visual effects like shadows , post processing etc..
it's not a game actually, u can consider it as an open BETA i made it to understand the basics of making a 3D game
I hope you like it since it's my first try in 3D and i've got no knowledge in this i've just started to learn !!
i really thank you for your support !! move with : A S D W
collect the coin and trade with the sharkman with : E
shoot : Left Click
Reload : R
ENJOY!!
If you wanna support me to work on new projects i would really appreciate it
