this is how i made my game:

the first thing is that i wanted the game to be complete 

so the first problem i faced was the main menu

( making the main menu ) :

i had to make the main menu and the intro to the story

to let the player know what's happening

so instead of making 2 different scenes i made the intro to the story that transitions to the main menu

with a beautiful calm background instead of just colors

the second problem :

( making the player know the controls) :

i needed a creative way of telling the controls to the player

in the story the protagonist is a new hunter who doesn't know anything about hunting.

so he meets a hunter and the hunter tells him the way of how hunting works(  which is the controls of the game).

the third problem

the element of surprise :

*don't read this unless you have finished my game*

the player keeps looking for the boss .

trying hard to prevent him.

until he has to kill a lot of people to find the boss.

only to find out that he is the boss.

fourth problem :

feelings :

i had to make the player attached to the story 

feeling every emotion

so i used music according to the mood of people in the world.

the final problem :

the game felt somehow inactive

it needs somethins

and it was my first time focusing on sound effects

i used a lot with music

and this made my game finally a complete game

i hope this made you learn something from me.

good luck.
