The Lost Coins - a 1st person adventure game

Hello, a week ago, i didn’t know what Unity was, today i’m following a Unity 3D (Beginning 3D Game Development with Unity) i’ve read about 15% of it, and then said, let’s make a little game.

Story:
A legendary bag of Golden Coins was lost, the legend says who owns all the coins can rule the world, buy anything he wants, sits on any throne and become the most powerful man that has ever lived.(boring, right?)

The Quest:
A young adventurer(Kris) heard about the legend from his grandfather, after the old man died starving because of a cruel king, Kris swore to find those lost coins and avenge his grandfather.

Gameplay:
Unlike the story, it’s pretty simple, look for the 15 coins in the terrain to win.

Controls:
-WASD/ Arrows are used to move the player
-Space to jump
-Mouse Right Button: hold to move the camera
-Mouse Left Button: pick up coins

It’s not as fun as Asphalt 7 or Battle Field, but you can at least enjoy the sight!

All constructive criticism is welcome, please know that i’m still a beginner, i’m counting on you to suggest future plans for this project, because i still don’t know what to do next.
