Unity 3D Game Design Document

This document outlines the design of a 3D popping balloons game built using Unity. The game is designed to be simple yet challenging, targeting a broad audience. The core gameplay involves popping balloons as they ascend the screen within a time limit. Each level increases in difficulty, and players earn rewards like extra 'souls' (continues) and power-ups. The game includes features like saving progress, pausing, and sound effects. The document includes a visual sketch of the game's screen design and details the game's goal, playability, target market, and genre (puzzle game).

Game Description
Introduction
I’m writing this document to describe the 3D Game which I will be developing using Unity
and plan it out. Planning the game out will make it easy for me to start the development as I
will know what I’m developing exactly because it’s all already written in this document. If I
ever forget the design of the game or anything else, then I can just get back to this
document.
Overview
The game I’m going to be developing is going to be a simple game, easy to play and not hard
to develop as I’m still new to Unity, therefore I didn’t want my game to be hard to create.
The game will be Popping balloons game. The user needs to pop as many balloons as they
can in the shortest time possible to win and move to the next level. The balloons are going
to keep moving from bottom to top so the player need to pop the top ones fast before the
bottom new ones come. There is going to be a specific time for each level and the player has
to pop all of the balloons before the time finishes to win the level. It’s going to start with 30
seconds and the seconds will go less each time we go up with the levels. There will be a
hidden surprise in some balloons when they are popped. It could be a good surprise or a
bad one, the player will not know until they pop it! Sometimes they get more souls, more
money or they can get less time! The player can use the Moues button to pop the balloons.
The game goal or the aim of my game is to entertain people and improve their focusing and
balancing skills, teaches them how to reach goals and stay on track and move fast. If the
player doesn’t click on the right button at the right time, then the balloons will not get
popped and will go and the new ones will replace them. therefore, the player will lose and a
message will appear saying “Game over” including two buttons titled as “Try Again” to
replay the game again and try to win and get to the next level or “Exit” to exit the game. The
game has levels meaning when the player reaches the end and pop all of the balloons and
no more balloons start appearing then they’ll win (A message will appear saying “You’ve
won!”) and go to the next level. The further the player goes with the levels, the harder the
game will get.
The playability of the game will be very simple, everyone can play it as it’s very easy to play,
and it just requires the player to focus. The player will only be using the four buttons (left,
right, up and back). The game will be very fun to play as it involves levels which will make
the player want to play it more and reach the highest levels. Also, it includes background
music for the player not to get bored as well as happy sound when the player wins and sad
sound when the player loses. Colourful background and images will be included in the game
as well.
Even though the game is easy to play, however it’s hard to reach the end of the level and
win but it’s not impossible. It’s a very challenging game, it will include 5 levels and the levels

get harder and harder each time the player go, however reaching the end of the 5 levels is
possible.
Every level the player completes and win, will get a reward which is 5 new Souls (these souls
will allow the player to carry on with playing the game after losing from the same point and
location where the given time has finished. Otherwise if they have zero souls, they’ll have to
replay the game from the start. Another reward is giving Powers such as popping a whole
line of balloons automatically which will save the player time.
If the player decides to leave the game and exist it and come back to it some other time and
carry on with the levels without the need of starting from level 1, then they can just Click on
the “Save” button and then “Exit”. Another good feature is they can click on the button
“Pause” to stop the game if they wanted a break.
After I’ve finished with developing the game, I will make sure that I test it very well to see if
it works as I planned it to or not. If I find any errors or things need to be changed or
improved, then I should change them and fix the errors before present the game to the
audience.
Target market
The game target market is literally everyone that want to play an entertaining game and is
able to focus. The game is not targeted to certain audience or ages, both genders can play it
and all ages. I’ll be selling it to everyone that’s interested in playing challenging and fun
games.
